About

  • SHO Weather is now primarily a weather generation script which generates quasi-realistic weather using real weather data for each track location
  • The generation script outputs GTR2-compatible weather files in bulk
  • These weather files are being integrated by The Iron Wolf in-game by adding options to the in-game Rainfall selector along with the Crew Chief GTR2 Enhancements Plugin

Contribute by Donating to Buy a Specific Location

PayPal USD $10 to paypal@shovas.ca and the location of your choice and I'll purchase it from OpenWeatherMap.org and add it. I'll be able to purchase full 1979 to 2023 data and integrate it with the mod.

Or you can purchase it yourself and send me the weather data. If you purchase yourself, check with me first about what locations are already covered, and be sure to select Date Range 01-01-1979 to 31-12-2023, All Weather Parameter, Kelvin Units, CSV File Format, Download: File per location.

All of this will be packaged in a "just works" weather feature by The Iron Wolf with the the Crew Chief GTR2 Enhancements Plugin where real weather data can chosen in-game using new options applied to the Rainfall selector.

Changes

24050501

  • Average weather generated for each GTR2 original track location based on real weather data
  • Launcher updated to allow launching with a random track's weather file

Install

  1. Extract to GTR2 folder
  2. Run __GTR2__Start__Weekend.cmd and choose desired Weekend Weather
  3. Choose "Changeable" for Rain option when starting your session

Weather will now progress per the custom UserData\Log\weather.txt file put in place by the cmd script.

Launcher

The launcher is a simple cmd script that handles swapping in and out custom weather files with the stock UserData\Log\weather.txt file.

The launcher handles setting the read-only attribute which prevents GTR2 from re-generating the file every session. It then undoes this when you exit GTR2 so everything goes back to normal.

Weather

GTR2's original weather generation algorithm is very uninteresting and you'll rarely see the weather change in a single session.

These custom weather files create more interesting weather scenarios in each session which basically means that there will be some kind of weather change in each session.

Autosim Weather Generator

The Autosim Weather Generator is available from eSports-racing.de and still works on Windows 10(*).

  • It was working fine until I installed Visual Studio with .NET and now it seems to be acting up. So, you may have to uninstall Visual Studio and/or those .NET packages to see it work.

Here's a demonstration of the app:

Here's what one weather set looks like in the app:

Real Weather Data

I purchased real weather data from openweathermap.org for all of the original GTR2 track locations. Anyone can purchase any location for USD $10 per location from openweathermap.org.

I'm providing it here in case anyone is interested in making projects out of the data.

The data license is a Creative Commons-like attribution license which means you're basically free to do anything you just have to attribute the license.

See Modernizing_GTR2_with_the_Crew_Chief_GTR2_Enhancements_Plugin#Real_Weather for tracks covered so far and tracks planned for the future.

Weather Generation Script

I have a weather generation script up and running in PHP which generates GTR2 weather files using the OpenWeatherMap data to find min/max/avg temps, humidity, dry/rainy/stormy and generate weather files that generally reflect realistic weather for the track location.

I plan to release the generation script and the generated weather files in upcoming releases.

Weather File Troubleshooting

  • Ensure Rainfall Changeable in-game
  • Symptom: Conditions/Forecast Icons stop working reliably.
    • Advice: Check file structure and syntax

Weather Notepad

These notes are generally tested and confirmed true 

File Structure and Syntax:
- Use spaces not tabs
- Use space indents to be safe and to be consistent with original weather.txt
- Check brackets
- End with empty blank line

Session vs Weather File Sections:
- Driving School = Dynamic Weather, not based on weather.txt (Confirmed with read-only dry weather.txt 240506)
- Time Trial = Open Practice (says so in Garage screen)
- Free Practice (Race Weekend) = Open Practice

Are HAT files caching weather file data and we might need to enable rebuilding? -->
- No. Still happens even when setting: Always Rebuild HAT="1" // Build HAT database everytime tracks are loaded (for development purposes)

Minute{} Blocks:
- Must specify numeric minute Minute=1.23, not just "Minute" or else GTR2 seems to think the last Minute is the initial conditions and the other Minutes are ignored 
- Minute=0.00{} is the initial conditions / It appears to be skipped / Must start with Minute > 0 or higher  (Minute=0.10 works)

Rainfall (in-game):
- Rainfall is not the same as Conditions
- Does Rainfall specify max Conditions? Ex. Rainfall 80% means max Conditions=80?
  - No, see Rainfall table below.
- Rainfall:
	Rainfall:	Track,		Conditions,				Forecast
	None: 		Dry,		Sunny,					Sunny
	10%:  		Damp, 		Cloudy w/Rain,			Cloudy w/Rain
	20%:  		Damp, 		Cloudy w/Rain,			Cloudy w/Rain
	30%:  		Damp, 		Cloudy w/Rain,			Cloudy w/Rain
	40%:  		Wet,		Cloudy w/Rain,			Cloudy w/Rain
	50%:  		Wet,		Cloudy w/Rain,			Cloudy w/Rain
	60%:  		Wet,		Cloudy w/Rain,			Cloudy w/Rain
	70%:  		Wet,		Cloudy w/Rain,			Cloudy w/Rain
	80%:  		Flooded,	Cloudy w/Thunderstorm,	Cloudy w/Thunderstorm
	90%:  		Flooded,	Cloudy w/Thunderstorm,	Cloudy w/Thunderstorm
	100%: 		Flooded,	Cloudy w/Thunderstorm,	Cloudy w/Thunderstorm
- Unable to check Rainfall level vs weather.txt file because Rainfall < Changeable doesn't generate weather.txt

Temperature:
- Default Temperature Progression: Ambient 20+, Track: 22+

Conditions Icon (Conditions: Sunny/Rainy/Stormy):
- Conditions is not the same as Rainfall in-game
- Weather.txt Conditions - Confirmed 240318: 
	0-61 Sunny (Sun)
	62-90 Rainy (Cloud w/Rain)
	91-100 Stormy (Cloud w/Rain and Lightning)
  - The real cut off between Sunny and Rainy and Rainy and Stormy is somewhere between the integer values (ie. 61.65 - 61.70, and 90.XX - 90.YY) but might as well just consider it an integer cut off of 61 and 62

Forecast Icon (Conditions: Sunny/Rainy/Stormy):
- Requires Minute{} block
- When no Minute{} blocks are specified, or if there are no more Minute{} blocks remaining, then Forecast appears to indicate a return to initial session Conditions

Track Wetness (Dry/Damp/Wet/Flooded):
- Track wetness (Dry/Damp/Wet/Flooded) is related to Conditions but is not the same as Conditions (Sunny/Rainy/Storm) (Confirmed 240318)
  - But a session's starting wetness does seem to be directly related to initial Conditions. That is, a track is immediately Dry/Damp/Wet/Flooded based on a session's immediate starting Conditions.
- Track wetness floods and drains dynamically based on Conditions, temperature, time, and total accumulating laps (the more AI the faster draining progresses)
- Track wetness does not progress (drier or wetter) by On/OffPathWetness in Minute{} progression.
  - It seems to be based on time, Conditions, temperature, and number of laps (the more AI the faster)
- Track Wetness Levels:
	0-5 Dry
	6-35 Damp
	36-75 Wet
	76-100 Flooded

Starting Weather vs Conditions
- Tested at Donington GP 2004 (Confirmed 240513)

Mapping GTR2 Conditions to AMS2 Weather Forecasts:

0-61: Clear
62-70: Overcast
71-80: Light Rain (Dry/Damp Track)
81-84: Rain (Wet Track)
85-92: Storm (Wet Track)
95-100: Thunderstorm (Flooded Track)

Real Time Weather and Time Scaled Weather:
- Real Time: Weather file Minute{}s occur at real time speed regardless of Race Weekend Distance Factor or 24H Race Length Factor (Confirmed 240515)
  - Interestingly, Minute{}s do not actually appear to represent time but distance (eg. At Imola, rain came in at the same point even when I was much slower).
- Time Scaled: Weather file Minute{}s occur at Real Time speed for Practice/Qualify/Warmup sessions and at a speed factor of Race Weekend Distance Factor or 24H Race Length Factor (Confirmed 240515)
  - Ex. 100% Distance: Weather events occur at real time speed
  - Ex. 50% Distance: Weather events occur 2x faster
  - Ex. 24H Race Length: Weather events occur at real time speed
  - Ex. 12H Race Length: Weather events occur 2x faster
- Time Scaled Weather is not affected by Daylight Acceleration (Confirmed 240510)
- Game-generated weather.txt Warmup and Race sections never have Minute{}s
  - But Warmup and Race do respect Minute{}s if they have them
  - A 24H race would need 1440 Minute{} blocks then
  - Tested Race Weekend with Changeable weather and no Minute{}s in Warmup and Race and it did not progress weather like I see in 24H races so there's some difference there
- 24H Race Game Generated Weather Files
  - 24H weather.txt does not have Minute{}s for Warmup or Race but I do see variable weather Conditions and Forecast going through Prac/Qual/Warm/Race
    - I guess Changeable weather under 24H is handled inside the game
  - Real Time weather.txt has many more Minute{}s with a much more granular Minute{} progression in steps of 1-2 minutes each
  - Time Scaled weather.txt has much fewer Minute{}s with a broader Minute{} progression, in steps of ~10 minutes each
  - Real Time weather.txt has more variability in Conditions (ex. 0-40)
  - Time Scaled weather.txt has less variability in Conditions (ex. 65-74)
  - Both Real Time and Time Scaled AmbientTemp seems to have a +/- 10C range
  - Examples:
    - Hockenheimn 24H:
      - Session lengths: 90/90/60/45/15/1440
      - Minute{}s: 90/90/60/45/0/0 (Warmup and Race had no Minute{} blocks)
    - Monza 24H:
      - Session lengths: 90/90/60/45/15/1440
      - Minute{}s: 90/90/60/45/0/0 (Warmup and Race had no Minute{} blocks)
  - Testing:
    - Weather.txt is generated once at beginning of 24H, it doesn't get rewritten each session
    - Weather.txt persists after exiting GTR2, so no need to alt-tab out and copy&paste the file to save it
- Conclusion:
  - Time Scaled Weather's purpose is to simulate longer weather patterns in shortened sessions
    - In other words, fewer weather events that are longer in duration rather than many weather events of shorter duration
  - Nothing seems to suggest it allows for scaling up limited weather.txt Minute{}s to sessions with more minutes
    - Meaning, you should have enough Minute{}s for the session length (eg. 60min = 60 Minute{}s, 3h/180min = 180 Minute{}s, 24H/1440min = 1440 Minute{}s)

To Be Confirmed:
- Weather Minute{}s are NOT about TIME, they're about DISTANCE
- True for Real Time AND Time Scaled or just Time Scaled? Because seems to conflict with observations above about Real Time.

Session Length vs Minute{}s:
- At the end of a session, when there are more Minutes{}s then session minutes, weather keeps progressing through Minute{}s 
- When there are less Minute{}s than session minutes, weather stops at last Minute{} and there are no other changes
- Applies for Real Time and Time Scaled Weather
- Basically, weather always plays through right to the end

Weather Scratchpad

These notes may not be tested or confirmed true 

TBD: Forecast is the last minute of the session for Practice1 45min(?)
- I don't think so. It might be something like the next Conditions change (eg. Sunny to Rainy or Rainy to Stormy or any sequential combo of those)
  - There may be something weird about 'minimum threshold of change' to update the Forecast icon
- Race 60min: Forecast is Minute 1
  - Race is special: Time is stopped until you start race, then you can't get back to the timing screen with the weather forecast
  - Any Minute with a different Conditions?
Session:
- Weather start offset by 30sec in sessions? Something's going on with a delay...

- Nope: I bet I could include and progress any of the parameters inside Minute{} blocks (eg. OnPathWetness, OffPathWetness)
  ^ Scratched: Wetness does not seem to progress in Minute{} blocks.
    - But Wetness does progress so it seems it's a function of time-conditions-temperature and those do progress in Minute{} blocks
 
Weather seems to interpolate between Minute{}s in some fashion although it's difficult to say how or what ratio, curve, or function is being applied:
- In a 15min Warmup with Real Time Weather:
  - Stormy->Sunny Minute=0.10:  Becomes clear around --:--
  - Stormy->Sunny Minute=1.00:  Becomes clear around --:--
  - Stormy->Sunny Minute=2.00:  Becomes clear around 14:40
  - Stormy->Sunny Minute=3.00:  Becomes clear around 14:15
  - Stormy->Sunny Minute=4.00:  Becomes clear around 13:45
  - Stormy->Sunny Minute=5.00:  Becomes clear around 13:30
  - Stormy->Sunny Minute=10.00: Becomes clear around 11:30
  - Stormy->Sunny Minute=15.00: Becomes clear around 9:30
  - Stormy->Sunny Minute=20.00: Becomes clear around 7:30
  - Stormy->Sunny Minute=25.00: Becomes clear around 5:30
  - Stormy->Sunny Minute=30.00: Becomes clear around 4:00
  - Stormy->Sunny Minute=35.00: Becomes clear around 2:00
  - Stormy->Sunny Minute=40.00: Becomes clear around 0:00
  - Warmup{} in weather.txt:
    Warmup
    {
     Conditions=100.00
     AmbientTemp=20
     Minute=15
     {
      Conditions=0.00
     }
    }
  - Time Scaled Weather seems to act the same as Real Time Weather
  - Time Scaled Weather: 10min warmup, 5min weather: Stopped on minute 5 and held the weather
  - Real Time Weather: 10min warmup, 5min weather: ...
  - Pit camera and Conditions Icon seem to be in sync
  - Minute=0.00{} is the initial conditions / It appears to be skipped / Must start with Minute=1.00{} or higher

5 Minute{}s +20 steps:
2.5m to Rainy, 4m5s to Stormy for both Real Time and Time Scaled Weather
- Minute 3 = 60 Conditions
- Minute 4 = 80 Conditions

10 Minute{}s +10 steps:
6min to Rainy, 9min to Stormy for both Real Time and Time Scaled Weather
- Minute 6 = 60 Conditions
- Minute 8 = 80 Conditions

15 Minute{}s +6.666 steps:
9min to rainy, 13min to Stormy for Real Time and Time Scaled Weather
- Minute 9 = 60 (59.994) Conditions
- Minute 13 = 80 (86.658) Conditions

30 Minute{}s +3.333steps:
Never gets to rain, never gets to Stormy on Real Time or Time Scaled Weather (
- 10m45s to *Forecast* rainy but never gets there
  - Minute 18 = 60 (59.994) Conditions
