Center. http://support.weblakes.com/Resource/td3505.pdf</Reference><Summary><Abstract>This product consists of meteorological data from 105 Arctic weather stations and 137 Antarctic stations, extracted from the National Climatic Data Center (NCDC)'s Integrated Surface Hourly (ISH) database. Variables include wind direction, wind speed, visibility, air temperature, dew point temperature, and sea level pressure. Temporal coverage varies by station, with the earliest record in 1913 and the latest in 2002. Data are in tab-delimited ASCII text format, with one file per station and year. Graphs of meteorological variables throughout the time series accompany the ASCII data.</Abstract></Summary><Related_URL><URL_Content_Type><Type>VIEW RELATED INFORMATION</Type></URL_Content_Type><URL>https://nsidc.org/sites/default/files/nsidc-0190-v001-userguide.pdf</URL><Description>Historical Arctic and Antarctic Surface Observational 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/nsidc0190_surface_obs_v1/</URL><Description>HTTPS</Description></Related_URL><Metadata_Name>CEOS IDN DIF</Metadata_Name><Metadata_Version>VERSION 9.9</Metadata_Version><DIF_Creation_Date>2004-01-07</DIF_Creation_Date><Last_DIF_Revision_Date>2026-03-03</Last_DIF_Revision_Date><Extended_Metadata><Metadata><Group>NSIDC</Group><Name>Version Summary</Name><Value/></Metadata><Metadata><Group>NSIDC</Group><Name>Minor Version</Name><Value/></Metadata><Metadata><Group>NSIDC</Group><Name>Current Version</Name><Value>1</Value></Metadata><Metadata><Group>NSIDC</Group><Name>Level of Service</Name><Value><Level>Basic</Level></Value></Metadata><Metadata><Group>NSIDC</Group><Name>Full Dataset Citation</Name><Value>Stroeve, J. &amp; Shuman, C.
