G02189 Zhang, T. Z. and O. W. Frauenfeld. 20110217 Boulder, Colorado USA NSIDC: National Snow and Ice Data Center http://nsidc.org/data/g02189.html http://dx.doi.org/10.7265/N5C24TC5 This data set includes soil temperature data from boreholes located at five stations in Russia: Yakutsk, Verkhoyansk, Pokrovsk, Isit', and Churapcha. The data have been compiled into five Microsoft Excel files, one for each station. Each Excel file contains three worksheets: <ul> <li><strong><em>G02189info</em></strong> worksheet: Contains the same content in each Excel file - lat/lon info and notes on the stations</li> <li><strong><em>Jan soil & surface temp</em></strong> worksheet: Contains winter (January) soil temperature and air temperature (except for the Churapcha Excel file that only contains soil temperature - air temperature was not available)</li> <li><strong><em>Jul soil & surface temp</em></strong> worksheet: Contains summer (July) soil temperature and air temperature (except for the Churapcha Excel file)</li> </ul> There are two different versions of the Excel files: a complete version and a subsetted version. Both versions exist for each of the five stations for a total of 10 files. The complete versions of the files reside in the directory called <em>complete</em> and have the word <em>full</em> in their filename. These files contain borehole temperature data at all available standard depths: 0.2 m, 0.4 m, 0.6 m, 0.8 m, 1.2 m, 1.6 m, 2.0 m, 2.4 m, and 3.2 m. The subsetted versions of the files reside in the <em>subset</em> directory and have <em>subset</em> in their filename. These files contain data from the 0.8 m and 3.2 m depths only. Missing data are indicated by the value <em>-999.0</em>. The complete version is more applicable to scientific investigation. The subset version is provided for K-12 teachers and is featured in a classroom activity called <a href="http://nsidc.org/frozenground/classroom/permanent_permafrost.html">"How Permanent is Permafrost?"</a> We have included air temperature measured at these five stations when it is available. There are two sources for the surface air temperature data: <a href="http://dss.ucar.edu/datasets/ds570.0/">NCAR World Monthly Surface Station Climatology, 1738-cont</a> and <a href="http://www.ncdc.noaa.gov/ghcnm/">NOAA Global Historical Climatology Network (GHCN) Monthly</a> data set. These two sources both draw on the same single original source: data from the <a href="http://www.wmo.int/pages/index_en.html">World Meteorological Organization</a> (WMO) station network. The complete files have data from one or both sources, while the subset files only include data from the source with the most complete record. These data are being offered as is. NOAA@NSIDC believes these data to be of value but is unable to research and document these data as we do most data sets we publish. scientific research 18800101 20001231 publication date Complete Unknown 125.3 133.4 67.6 60.8 NASA Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > Cryosphere > Frozen Ground > Permafrost EARTH SCIENCE > Cryosphere > Frozen Ground > Soil Temperature EARTH SCIENCE > Land Surface > Frozen Ground > Permafrost EARTH SCIENCE > Land Surface > Frozen Ground > Soil Temperature EARTH SCIENCE > Land Surface > Land Temperature > Land Surface Temperature None ISO 19115 Topic Categories climatologyMeteorologyAtmosphere None Boreholes Borehole Temperatures International Permafrost Association Land Surface Temperature Permafrost Permafrost borehole temperatures Permafrost temperature Soil Temperature NASA Global Change Master Directory (GCMD) Location Keywords Continent > Europe > Eastern Europe > Russia 5 NASA Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > Cryosphere > Frozen Ground > Permafrost NASA Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > Cryosphere > Frozen Ground > Soil Temperature NASA Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > Land Surface > Frozen Ground > Permafrost NASA Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > Land Surface > Frozen Ground > Soil Temperature NASA Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > Land Surface > Land Temperature > Land Surface Temperature None None NSIDC User Services National Snow and Ice Data Center mailing
