The Fertile Crescent has been steadily drying since 1931, and recent changes have exacerbated the trend.
Frost clings to an eddy covariance tower in Barrow, Alaska. The sensors measure methane emissions year round and are equipped with deicers to prevent them from malfunctioning in the Arctic's frigid temperatures. The tower also measures other meteorological variables, including air temperature, humidity, soil temperature, and soil moisture. (Courtesy S. Losacco)
Scientists with CARVE track methane emission in Alaska all year round.
Mean remotely-sensed active layer thickness (cm) near Barrow, Alaska. Data from http://dx.doi.org/10.3334/ORNLDAAC/1266.
Measuring changes in the thickness of the soil's active layer provides insight into climate change in the Arctic.
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.

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.
Map of Thermokarst Landscapes in Siberia and Alaska
New data map the distribution and carbon storage of thermokarst landscapes in the Arctic.
Methane concentrations during a CARVE flight on May 27, 2012.
Atmospheric gas concentrations measured over Alaska by the Carbon in Arctic Reservoirs Vulnerability Experiment (CARVE) are now available.

ABoVE aims to unravel the ways changes in boreal forests affect climate.
Mean net ecosystem production for 2006-2010 (from Turner et al., 2016).
Net ecosystem production (NEP) for the 2006–2010 interval on Pacific Northwest forestland reveals an overall carbon sink throughout the region.
