DescriptionThe CSR monthly land mass grids contain land water mass anomaly given as equivalent water thickness derived from GRACE time-variable gravity observations during the specified timespan in ASCII/netCDF/GeoTIFF formats. The Equivalent water thickness represents the total terrestrial water storage anomalies from soil moisture, snow, surface water (incl. rivers, lakes, reservoirs etc.), as well as groundwater and aquifers. A glacial isostatic adjustment (GIA) correction has been applied, and standard corrections for geocenter (degree-1) and C20 (degree-20) are incorporated. Post-processing filters have been applied to reduce correlated errors. From the RL06 version, all GRACE-FO products in the ASCII format have adopted the YAML encoding header, which is in full compliance with the PO.DAAC metadata best practices.

GRACE-FO
Platform
Name: Gravity Recovery and Climate Experiment Follow-On (GRACE-FO)
Orbit Period: -1 minutes
Inclination Angle: 89 degrees
Ascending Node: 1970-Jan-01 00:00:00

GRACE-FO ACC
SENSOR
Name: GRACE-FO SuperSTAR Accelerometer (GRACE-FO ACC)
Swath Width: -1 km
Description: The accelerometer, located at the center of mass of each satellite, measures all non-gravitational forces acting on each satellite. These forces include air drag, solar radiation pressure, and attitude control activator operation.

GRACE-FO KBR
SENSOR
Name: GRACE-FO K-Band Ranging System (GRACE-FO KBR)
Swath Width: -1 km
Description: This instrument precisely measures the changes in the separation between the two GRACE satellites using phase tracking of K- and Ka-band signals sent between the two satellites

GRACE-FO SCA
SENSOR
Name: GRACE-FO Star Camera Assembly (GRACE-FO SCA)
Swath Width: -1 km
Description: The SCA (Star Camera Assembly) consists of three temperature controlled CCD star cameras mounted to the accelerometer, along with the respective baffle assemblies. The STR delivers its video frames to the OBC, which then computes the attitude quaternions. The OBC also acts as the power and command/control interface to the STR. Once switched on and initialized, the STR proceeds with automatic coarse attitude acquisition and then on to fine attitude derivation.
