Daymet 2018 Data Now Available

Daymet provides high-resolution surface meteorology data for North America.

Daymet provides high-resolution surface meteorology data for North America. The figure shows annual data for the year 2018; Left: Mean maximum daily temperature, Middle: Total precipitation, Right: Mean minimum daily temperature. Daymet data is archived and distributed by the ORNL DAAC.

The popular Daymet Version 3 daily surface weather and climatological summaries have been updated to include all years 1980 - 2018 for continental North America, Puerto Rico, and Hawaii. Daymet output variables include the following parameters: minimum temperature, maximum temperature, precipitation, shortwave radiation, vapor pressure, snow water equivalent, and day length.
