Mean daily daytime average CO2 concentration [ppm] in the boundary layer in June 2010 from the WRF model.
New model outputs from the Penn State WRF-Chem version of the Weather Research and Forecasting (WRF) model estimate the hourly CO2 concentration in the atmosphere.

AirMOSS radar returns at the BERMS site in Saskatchewan, Canada, on April 22, 2013, rendered as a color image. The AirMOSS radar is a P-band fully polarimetric synthetic aperture radar (SAR) that can penetrate through vegetation and soil to depths of approximately 1.2 meters.
AirMOSS used ultra-high frequency synthetic aperture radar to measure root-zone soil moisture at sites across North America from Canada to Costa Rica.
Daymet V3 cross-validation tile-wide summary statistics for 2010 maximum temperature. daymae: mean absolute error for single day predictions.
How accurate is Daymet? Cross-validation statistics for Daymet Version 3 are now available for each of the 2-degree by 2-degree tiles.
Daymet V3 average annual minimum temperature for 1980 and 2015 for a subset of the Daymet domain in Alaska and western Canada.
Annual and monthly climatologies for 1980-2015 for minimum and maximum temperature, precipitation, and vapor pressure are now available for Daymet V3.

The ORNL DAAC's MODIS subsetting tool was recognized by the Federal Geographic Data Committee.
Daymet V3 total precipitation for January (top) and August (bottom) of 2000 for a subset of the Daymet domain in eastern North America.
Version 3 expands Daymet coverage to the entire North American continent based on an improved algorithm, more robust ground-based weather station inputs, and additional climate networks.
