    This dataset contains the Global Mean Sea Level (GMSL) trend generated from the Integrated Multi-Mission Ocean Altimeter Data for Climate Research Version 5.2. The GMSL trend is a 1-dimensional time series of globally averaged Sea Surface Height Anomalies (SSHA) from TOPEX/Poseidon, Jason-1, OSTM/Jason-2, Jason-3, and Sentinel-6A that covers September 1992 to present with a lag of up to 4 months. The data are reported as variations relative to a 20-year TOPEX/Jason collinear mean. Bias adjustments and cross-calibrations were applied to ensure SSHA data are consistent across the missions; Glacial Isostatic Adjustment (GIA) was also applied. The data are available as a table in ASCII format. Changes between the version 5.1 and version 5.2 releases are described in detail in the user handbook.

    An inventory of NASA's airborne and field campaigns for Earth Science SARP2009Data SARP2009Data is the data collected onboard the NASA DC-8 aircraft during the 2009 deployment of the Student Airborne Research Program (SARP) mission. Data collection for this product is complete. NASA’s SARP is an eight-week summer internship program for rising senior undergraduate students to acquire hands-on research experience in all aspects of a scientific field campaign. Active since 2009, SARP utilizes one of the major NASA Airborne Science Program flying science laboratories that are used to study Earth system processes, calibration/validation of space-borne observations, and prototyping of instruments for possible satellite missions. Participants assist in the operation of instruments onboard the aircraft to sample atmospheric gases and/or to image land and water surfaces in multiple spectral bands. Students also participate in collecting measurements at field sites. Research [...]
