Currently, the repository covers ERA5, ERA-Interim, MERRA-2, and the NCEP/NCAR Reanalysis 1. The tropopause data files provide geopotential height, pressure, temperature, and water vapor volume mixing ratio for the WMO 1st and 2nd tropopause, the cold point, and the dynamical tropopause.</dcterms:description><dcterms:subject>Computer and Information Science</dcterms:subject><dcterms:subject>Earth and Environmental Sciences</dcterms:subject><dcterms:subject>atmosphere, tropopause, meteorological reanalyses</dcterms:subject><dcterms:language>English</dcterms:language><dcterms:contributor>Hoffmann, Lars</dcterms:contributor><dcterms:dateSubmitted>2021-06-17</dcterms:dateSubmitted><dcterms:temporal>2000-01-01</dcterms:temporal><dcterms:temporal>2018-12-31</dcterms:temporal><dcterms:type>meteorological data</dcterms:type><dcterms:license>CCBY</dcterms:license></metadata>
