Sites in Version 2 of the Permafrost Dynamics Observatory Project product. Green = data delivered in Version 2. Red = not delivered in Version 2 but will be delivered in future version. Yellow = not processed due to only L-band data being available.
Estimates of seasonal subsidence, ALT, vertical soil moisture profile, and uncertainties at a 30-m resolution for 28 sites across the ABoVE domain are now available.

A new dataset from the Atmospheric Tomography Mission (ATom) compares airflow and aerosol particles.
ACT-America 2019 summer airborne campaign showing the flight paths for the two aircrafts and location of ground towers. Flights were concentrated on three study domains: northeast, south-central, and midwest regions of the United States.
A new version of merged in situ atmospheric trace gases and flask data from the Atmospheric Carbon and Transport-America project is now available.
Circles mark the locations of the 139 selected profiles sampling the remote troposphere. Circle color indicates HCHO column densities integrated over each ATom profile. Data are overlain on global gridded OMI HCHO column densities averaged over the mission. From Wolfe et al. (2019) (see dataset references).
New data from NASA's Atmospheric Tomography Mission (ATom) provide hydroxyl and formaldehyde column density in the remote troposphere.
