The spectral  hygrometer provided the ratio Rsh=L(935)/L(880), where L(935) is  the radiance at 935 nm. The measurement is acquired by aiming the  optics at the sun. The Spectral Hygrometer data files consist of  data acquired on September 29, 1989. Columns are time in PDT,  ratio of L(935) / L(880) for instrument SH015, time in PDT and  corresponding ratio for instrument SH004.", "identifier": "urn:nasa:pds:context_pds3:data_set:data_set.fexp-e-shyg-3-rdr-opt-dep-v1.0_4u7f-zw3z", "issued": "2021-05-21", "keyword": ["earth", "geologic-remote-sensing-field-experiment"], "landingPage": "https://pds.nasa.gov/ds-view/pds/viewDataset.jsp?dsid=FEXP-E-SHYG-3-RDR-OPT-DEP-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": "FIELD EXP E SHYG CALIBRATED RDR \n                                     OPTICAL DEPTH V1.0"}
