New on the blog: we're discussing our experience using #Kerchunk to improve access times to short-range streamflow predictions generated by NOAA's #NationalWaterModel Predictions Dataset.

Did you know Azavea is working with #NOAA to store large amounts of #NationalWaterModel data using cloud-optimized formats like #Parquet and #Zarr?

Learn more in our our blog focused on benchmarking: https://www.azavea.com/blog/2022/09/22/benchmarking-zarr-and-parquet-data-retrieval-using-the-national-water-model-nwm-in-a-cloud-native-environment/
