Plot Description:

This plot presents daily estimates of solar radiation for a given year for the 'climodat' stations tracked by the IEM. These stations only report temperature, precipitation, and snowfall, but many users are interested in solar radiation data as well. So estimates are pulled from various reanalysis and forecast model analyses to generate the numbers presented. There are four sources of solar radiation made available for this plot. The HRRR data is the only one in 'real-time', the MERRAv2/NARR lag by about a month, and the ERA5 Land lags by 8-9 days.

Based on a sampling of recent timings for this application, plot generation time has averaged 2 seconds. Hold on for the plot is generating now!
