Spatial Coverage
Smoothed, regional average percentage of 3km grid cells that have at least one eBird checklist for a given week. At values less than 0.0003, we remove all predictions from all species models. At values greater than 0.01, we put the assumed zero gray in the background of the results. Having 5% lets us make assumptions about species absence in the actual species modeling process (this level is a good indicator of lots of data).* Data is aggregated at small scales.
