Instruments flown over Antarctica include a cabin pressure transducer, a 2-stage and a 3-stage hygrometer, a total air temperature sensor, and an infrared surface temperature pyrometer. The data files contain measurements for 36 meteorological, surface characteristic, and positional variables. The data were collected as part of Operation IceBridge funded campaigns.</Abstract></Summary><Related_URL><URL_Content_Type><Type>VIEW RELATED INFORMATION</Type></URL_Content_Type><URL>https://nsidc.org/sites/default/files/iamet1b-v001-userguide.pdf</URL><Description>IceBridge NSERC L1B Geolocated Meteorologic and Surface Temperature Data, Version 1 User Guide</Description></Related_URL><Related_URL><URL_Content_Type><Type>GET DATA</Type></URL_Content_Type><URL>https://daacdata.apps.nsidc.org/pub/DATASETS/ICEBRIDGE/IAMET1B_NSERCmetXyMet_v01/</URL><Description>HTTPS</Description></Related_URL><Related_URL><URL_Content_Type><Type>PROJECT HOME PAGE</Type></URL_Content_Type><URL>https://nsidc.org/data/icebridge</URL><Description>IceBridge Product Web Site</Description></Related_URL><Related_URL><URL_Content_Type><Type>PROJECT HOME PAGE</Type></URL_Content_Type><URL>https://science.nasa.gov/mission/icebridge/</URL><Description>NASA IceBridge Mission</Description></Related_URL><Metadata_Name>CEOS IDN DIF</Metadata_Name><Metadata_Version>VERSION 9.9</Metadata_Version><DIF_Creation_Date>2010-08-03</DIF_Creation_Date><Last_DIF_Revision_Date>2026-08-20</Last_DIF_Revision_Date><Extended_Metadata><Metadata><Group>NSIDC</Group><Name>Version Summary</Name><Value>Initial release</Value></Metadata><Metadata><Group>NSIDC</Group><Name>Minor Version</Name><Value/></Metadata><Metadata><Group>NSIDC</Group><Name>Update Frequency</Name><Value>updated 2013</Value></Metadata><Metadata><Group>NSIDC</Group><Name>Current Version</Name><Value>1</Value></Metadata><Metadata><Group>NSIDC</Group><Name>Spatial Reference Systems</Name><Value><Spatial_Reference_System><SRID>EPSG:3031</SRID><Description>WGS 84 / Antarctic Polar Stereographic</Description></Spatial_Reference_System></Value></Metadata><Metadata><Group>NSIDC</Group><Name>Level of Service</Name><Value><Level>Standard</Level></Value></Metadata><Metadata><Group>NSIDC</Group><Name>Full Dataset Citation</Name><Value>Shetter, R., Buzay, E. &amp; Van Gilst, D.
