This dataset contains daily aggregations of environmental exposures collected from the ERA5 Climate Data Store aggregated to geographic polygons in Madagascar and Nepal as part of the Climate-Smart Public Health project of the Golden Lab group at Harvard T.H. Chan School of Public Health. Exposures include 2-metre temperature, dewpoint temperature, total precipitation, and soil moisture. Aggregations include basic statistics per day within geospatial "healthsheds". The healthsheds' geographies are provided directly by the respective governments.
