The data set consists of a table with the following columns: spacecraft latitude, longitude (degrees), accelerations, and altitude (km). The acceleration data were determined from differentiation of raw Doppler residuals and are expressed as units of mm/s**2. To obtain LOS gravity in milligals, accelerations need to be multiplied by 100. An acceleration of 1.20 mm/s**2, therefore, corresponds to 120 mgal, a large gravity anomaly.", "identifier": "urn:nasa:pds:context_pds3:data_set:data_set.vo2-m-rss-4-los-gravity-v1.0_qsq5-etz8", "issued": "2021-05-21", "keyword": ["mars", "pre-magellan", "viking"], "landingPage": "https://pds.nasa.gov/ds-view/pds/viewDataset.jsp?dsid=VO2-M-RSS-4-LOS-GRAVITY-V1.0", "license": "http://www.usa.gov/publicdomain/label/1.0/", "modified": "2025-07-17", "programCode": ["026:005"], "publisher": {"@type": "org:Organization", "name": "National Aeronautics and Space Administration"}, "references": ["https://pds.nasa.gov"], "theme": ["Earth Science"], "title": "VO2 MARS RADIO SCIENCE SUBSYSTEM RESAMPLED LOS GRAVITY V1.0"}
