These observations can detect regional mass changes of Earth's water reservoirs over land, ice and oceans. GRACE measures gravity variations by relating it to the distance variations between the two satellites, which fly in the same orbit, separated by about 240 km at an altitude of ~450 km. The monthly ocean mass grids contain ocean bottom pressure anomalies from GRACE time-variable gravity data processed by JPL relative to a time-mean. The bottom pressure anomalies are given in 'equivalent water thickness' (in ASCII format), so can be compared to sea level anomalies due to changes of water mass (reference density is 1027 kg/m^3).

They are related to but not fully explained by the three Milankovich cycles describing the eccentricity, precession (about the same as the Earth-Sun distance on June 21st), and tilt of the Earth relative to the ecliptic (http://www-istp.gsfc.nasa.gov/stargaze/Sprecess.htm). The most recent global deglaciation event, which marked the end of the most recent 100 kyr ice age cycle of the late Quaternary period began only 21,000 calendar years ago (Peltier 2004), just before the Milankovitch cycle, and was essentially complete by 6000 years ago, but relative sea level have continued to change, essentially everywhere on the earth's surface, due to this cause. This continuing variation of land and sea levels exists as a consequence of the earth's delayed viscoelastic response to the redistribution of mass on its surface that accompanied deglaciation. In regions that were previously glaciated, such as Canada and Northwestern Europe, relative sea level continues to fall at a rate that is primarily determined by the ongoing post-glacial rebound of the crust and which may exceed 1 cm/yr (in the southeast Hudson Bay region of Canada, this rate is near 1.1 cm/yr). Even at sites that are well removed from the centres of glaciation, however, the rates of relative sea level change that exist as a consequence of ongoing glacial isostatic adjustment are non-negligible (e.g., Peltier 1999)." description_attribution: http://podaac.jpl.nasa.gov/dataset/TELLUS_PGR_TXT doi: ~ end_time: 2000-01-01T00:00:00 href: http://52.38.26.42:8080/dataset/nasa-podaac-tellus_pgr_txt.yaml identifier: nasa-podaac-tellus_pgr_txt lat_max: 90 lat_min: -90 lon_max: 180 lon_min: -180 name: TELLUS POST GLACIAL REBOUND ASCII native_id: TELLUS_PGR_TXT processing_level: ~ publication_year: ~ release_dt: 2011-04-20T19:23:05 scale: ~ scope: ~ spatial_extent: ~ spatial_ref_sys: ~ spatial_res: ~ start_time: 0100-01-01T00:00:00 temporal_extent: ~ temporal_resolution: ~ type: ~ uri: /dataset/nasa-podaac-tellus_pgr_txt url: http://podaac.jpl.nasa.gov/dataset/TELLUS_PGR_TXT variables: ~ version: ~ vertical_extent: ~ - access_dt: ~ attributes: ~ cite_metadata: ~ data_qualifier: ~ description: "GDS2 Version -The Tropical Rainfall Measuring Mission (TRMM) Microwave Imager (TMI) is a well calibrated passive microwave radiometer, similar to the Special Sensor Microwave Imager (SSM/I), that contains lower frequency channels required for sea surface temperature (SST) retrievals. The TRMM is part of the NASA's mission to planet Earth, and is a joint venture between NASA and the Japan Aerospace Exploration Agency (JAXA) to measure precipitation, water vapor, SST and wind in the global tropical regions and was launched in 27 November 1997 from the Tanegashima Space Center in Tanegashima, Japan. The TRMM satellite travels west to east in a 402 km altitude semi-equatorial precessing orbit that results in day-to-day changes in the observation time of any given earth location between 38S and 38N. Remote Sensing Systems has produced a Version-4 TMI ocean SST dataset for the Group for High Resolution Sea Surface Temperature (GHRSST) by applying an algorithm to the 10.7 GHz channel through a removal of surface roughness effects. In contrast to infrared SST observations, microwave retrievals can be measured through clouds, which are nearly transparent at 10.7 GHz. Microwave retrievals are also insensitive to water vapor and aerosols. The algorithm for retrieving SSTs from radiometer data is described in \"AMSR Ocean Algorithm.\"" description_attribution: http://podaac.jpl.nasa.gov/dataset/TMI-REMSS-L2P-v4 doi: ~ end_time: ~ href: http://52.38.26.42:8080/dataset/nasa-podaac-tmi-remss-l2p-v4.yaml identifier: nasa-podaac-tmi-remss-l2p-v4 lat_max: 39.01 lat_min: -39.06 lon_max: 180 lon_min: -179.99 name: GHRSST Level 2P Global Subskin Sea Surface Temperature from TRMM Microwave Imager (TMI) onboard Tropical Rainfall Measurement Mission (TRMM) satellite native_id: TMI-REMSS-L2P-v4 processing_level: ~ publication_year: ~ release_dt: 2014-10-07T22:20:00 scale: ~ scope: ~ spatial_extent: ~ spatial_ref_sys: ~ spatial_res: ~ start_time: 1998-01-01T00:44:16 temporal_extent: ~ temporal_resolution: ~ type: ~ uri: /dataset/nasa-podaac-tmi-remss-l2p-v4 url: http://podaac.jpl.nasa.gov/dataset/TMI-REMSS-L2P-v4 variables: ~ version: ~ vertical_extent: ~ - access_dt: ~ attributes: ~ cite_metadata: ~ data_qualifier: ~ description: 'The Sensory Data Record (SDR) is similar to the GDR product except that it also contains waveforms, which are required for retracking.

The most obvious of these changes was a more or less steady increase in the significant wave height (SWH) from approximately cycle 162 onward that reached about 0.4 m when the switch was made from Alt-A to Alt-B in February 1999 (cycle 235/236). Changes in PTR are also likely to affect the range measurement at the centimeter level. The amount of this change is still under investigation. Tide gauge calibration of the entire TOPEX data set suggest that the net change in sea surface height was less than or approximately 1 cm from the PTR change. Changes to SWH and range will be determined by waveform retracking (usually simply called "retracking") using the method of Rodriguez (Ref. 7). Determining changes in range to much better than 1 cm and in SWH to better than 0.1 m became increasingly important as global change researchers attempted to determine sea level rise to better than 1 mm/yr globally and also to determine geographic patterns in the sea level change. The SWH is of interest not only as a geophysical variable but also because it is used in calculating the electromagnetic bias (EMB) that corrects the altimeter range. Furthermore, the EMB correction is different at the Ku and C band frequencies of the TOPEX altimeter, so that changes in EMB also cause changes in the estimate of the ionospheric correction. The original premise of the GCP was that all data would be corrected by retracking to be consistent with data from very early in the mission (before approximately cycle 100) when there were no observed changes in the altimeter. Retracking of cycles 021 through 026 showed systematic differences between the GDR values of SWH and range at both K and C bands that were functions of hemisphere and orbit direction. In order to preserve as much of existing analysis as possible, it was decided to attempt to keep retracking from perturbing the values for early cycles simply because of the difference between retracking and the GDR. Thus, "quadrant adjustments" to K and C range and SWH depending on hemisphere and orbit direction (north ascending, north descending, south ascending, south descending, abbreviated as NA, ND, SA, SD) were introduced. Since Jason is being calibrated to Alt-B, the usefulness of these adjustments to Alt-A (or to Alt-B, for that matter) will have to be determined after Jason Cal/Val. Finding a reliable way of estimating the PTR proved to be much more difficult than expected, so the GCP was still not released as Jason launch approached. It was then decided to add additional fields to the product to make the TOPEX data compatible with the Jason data. As indicated below, these "Jason compatibility" fields are named with a prefix of "jas_". Furthermore, in order to provide data quickly for global comparisons during Jason Cal/Val, the GCP software was modified to produce GCPs using just TOPEX (I)GDRs.' description_attribution: http://podaac.jpl.nasa.gov/dataset/TOPEX_GCP doi: ~ end_time: 2005-10-04T00:00:00 href: http://52.38.26.42:8080/dataset/nasa-podaac-topex_gcp.yaml identifier: nasa-podaac-topex_gcp lat_max: 90 lat_min: -90 lon_max: 360 lon_min: 0 name: 'TOPEX GDR Correction Product - GCP (Callahan)' native_id: TOPEX_GCP processing_level: ~ publication_year: ~ release_dt: 2011-01-21T17:10:13 scale: ~ scope: ~ spatial_extent: ~ spatial_ref_sys: ~ spatial_res: ~ start_time: 1993-02-28T00:00:00 temporal_extent: ~ temporal_resolution: ~ type: ~ uri: /dataset/nasa-podaac-topex_gcp url: http://podaac.jpl.nasa.gov/dataset/TOPEX_GCP variables: ~ version: ~ vertical_extent: ~ - access_dt: ~ attributes: ~ cite_metadata: ~ data_qualifier: ~ description: 'The TOPEX/POSEIDON GDR (Geophysical Data Record) contains global coverage altimeter data.
