GRACE Level 1B/2 Data Products Jan-2017

| The Gravity Recovery and Climate Experiment (GRACE) mission was a joint project
between NASA and DLR. The primary science objective of GRACE was to measure the Earth’s gravity
field and time variability with unprecedented accuracy. The secondary science
objective was to obtain approximately 150 very precise globally distributed
vertical temperature and humidity profiles of the atmosphere per day using the
GPS radio occultation technique. ESA offers access to worldwide GRACE data via the TPM scheme. Read more
