The passive radiometry measurement is accomplished in a novel fashion by monitoring the noise density at the output of the photodetector and solving for the amount of background light. The passive radiometry measurements provide images of Mars at 1064-nm wavelength over a 2 nm bandwidth with sub-km spatial resolution and with 2% or better precision under full illumination.", "distribution": [{"@type": "dcat:Distribution", "description": "Access the data via HTTPS", "downloadURL": "https://atrain.gesdisc.eosdis.nasa.gov/data/MAC/MAC02QS0.002/", "format": "HTML", "mediaType": "text/html", "title": "Download this dataset through a directory map"}, {"@type": "dcat:Distribution", "description": "Access the dataset landing page from the GES DISC website.", "downloadURL": "https://disc.gsfc.nasa.gov/datacollection/MAC02QS0_002.html", "format": "HTML", "mediaType": "text/html", "title": "This dataset's landing page"}, {"@type": "dcat:Distribution", "description": "CloudSat Data Processing Center", "downloadURL": "http://www.cloudsat.cira.colostate.edu/", "format": "HTML", "mediaType": "text/html", "title": "View information related to this dataset"}, {"@type": "dcat:Distribution", "description": "MODIS Project Home Page", "downloadURL": "https://modis.gsfc.nasa.gov/", "format": "HTML", "mediaType": "text/html", "title": "View information related to this dataset"}, {"@type": "dcat:Distribution", "downloadURL": "https://docserver.gesdisc.eosdis.nasa.gov/public/project/Images/MAC02QS0_002.png", "format": "PNG", "mediaType": "image/png", "title": "Get a related visualization"}], "identifier": "urn:nasa:pds:context_pds3:data_set:data_set.mgs-m-mola-3-prdr-l1a-v1.0_2n36-n7e9", "issued": "2018-06-26", "keyword": ["mars", "mars-global-surveyor"], "landingPage": "https://pds.nasa.gov/ds-view/pds/viewDataset.jsp?dsid=MGS-M-MOLA-3-PRDR-L1A-V1.0", "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": "MOLA PRECISION RADIOMETRY DATA RECORD"}
