SHO Weather

Image: GTR2 Start Weekend Launcher with preconfigured weekend weather for test days, Practice, Qualifying, and Race sessions

SHO Weather is just an experiment for now to see how far I can go with weather. In the first release, you can choose different weekend weather which I've tried to make feel consistent throughout the sessions of a race weekend.

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 GTR2 track locations. Anyone can purchase any location for USD $10 per location.

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.

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.

OpenWeatherMap Weather Database Files

In the download, you'll find the following files:
