Collage of dataset airborne imagery from AirSWOT, UAVSAR and the ASO lidar instrument provide examination of water level elevation estimates and changes.

Body
Five Pre-Delta-X Airborne datasets recently published provide sea water level profile and change derived from UAVSAR, AirSWOT, and lidar.

Body
NASA's Delta-X Mission combines airborne remote sensing and field measurements to analyze water levels, vegetation, and sediment to understand how and where the Mississippi River Delta is changing.

Body
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.

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).

Body

New data from NASA's Atmospheric Tomography Mission (ATom) provide hydroxyl and formaldehyde column density in the remote troposphere.
