United States, Mexico, Canada, Hawaii, and Puerto Rico. It is derived
from selected meteorological station data and various supporting data
sources.
Compared to the previous version, Daymet V3 uses an entirely new suite
of inputs including:
NASA SRTM DEM version 2.1.
\nLand/Water Mask: MODIS 250 MOD44W_v2.NASA_ORNL_
Horizon files derived from the SRTM DEM.
\nGround station weather inputs from several sources with QA/QC.
\nVersion V3
