   • Typical requests are for 2-week time windows of recent forecasts. If you need a longer time range for your evaluation or particular use case, please discuss this with your commercial contact.
4. Which weather data variables would you like to look at?
   • Weather variables are separated into distinct bundles. You can simply state the name of the bundles you are interested in having access to.
