The Laser Hygrometer measures in situ water vapor content using a tuneable laser emitting at 1.37 microns. Absorption at that wavelength is a function of water vapor content, thus measuring the amount of absorption in an open path beyond the aircraft boundary layer, a value of water vapor pressure is made. The maximum sampling rate is 8 Hz, but the instrument is normally configured through the software for a 1Hz sampling rate.", "distribution": [{"@type": "dcat:Distribution", "downloadURL": "https://search.earthdata.nasa.gov/search?q=c4djlh", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "http://ghrc.nsstc.nasa.gov/uso/ds_docs/camex4/c4djlh/c4djlh_dataset.html", "format": "HTML", "mediaType": "text/html"}, {"@type": "dcat:Distribution", "downloadURL": "https://ghrc.earthdata.nasa.gov/browseui/#pub/c4djlh__1/docs/TUTORIAL.pdf", "format": "PDF", "mediaType": "application/pdf"}, {"@type": "dcat:Distribution", "downloadURL": "https://ghrc.earthdata.nasa.gov/browseui/#pub/c4djlh__1/docs/jlh_summary.pdf", "format": "PDF", "mediaType": "application/pdf"}, {"@type": "dcat:Distribution", "downloadURL": "https://ghrc.earthdata.nasa.gov/browseui/#pub/c4djlh__1/docs/JLHfactsheet.doc", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://ghrc.nsstc.nasa.gov/home/field-campaigns/camex4", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://ghrc.nsstc.nasa.gov/home/about-ghrc/citing-ghrc-daac-data", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "conformsTo": "http://www.isotc211.org/2005/gmi", "description": "The metadata's original source.", "downloadURL": "https://cmr.earthdata.nasa.gov/search/concepts/C1979096272-GHRC_DAAC.iso19115", "format": "ISO", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "10.5067/CAMEX-4/HYGROMETER/DATA101", "keyword": ["earth-science-atmospheric-water-vapor-atmosphere-water-vapor-indicators-water-vapor"], "license": "https://www.usa.gov/government-works", "modified": "2026-04-06", "programCode": ["026:000"], "publisher": {"@type": "org:Organization", "name": "NASA/MSFC/GHRC"}, "spatial": "[\"CARTESIAN\",[{\"WestBoundingCoordinate\":-88.215,\"NorthBoundingCoordinate\":39.71,\"EastBoundingCoordinate\":-58.635,\"SouthBoundingCoordinate\":16.5317}]]", "temporal": "2001-08-18/2001-09-25", "theme": ["Earth Science"], "title": "CAMEX-4 JPL LASER HYGROMETER V1"}
