Given some input context (e.g., radar fields, envionrmental parameters), predict how much rain fell at a rain gauge site over some period of time. Concretely, we've gather and QC'd data from **220 tipping bucket gauges** through Nevada for the years 2021-2026. These readings are then used as ground-truth for **~400k samples**, temporally and spatially aligned to 13 MRMS radar feilds and 39 HRRR envionrmental parameters. This dataset can therefore support training diverse QPE models (point -> point, local-spatial context -> point, etc.) ### Region of Interest ---
