Abstract:
Abstract. Relict permafrost presents an ideal opportunity to
understand the impacts of climatic warming on the ground thermal regime
since it is characterized by a mean annual ground temperature close
to 0 ∘C and relatively thin permafrost. The long-term and continuous
observations of permafrost thermal state and climate background are of great
importance to reveal the links between the energy balance on hourly to
annual timescales, to evaluate the variations in permafrost thermal state
over multiannual periods and to validate the remote sensing dataset. We
present 11 years of meteorological and soil data from the Mahan Mountain
relict permafrost site of northeastern Qinghai–Tibet Plateau. The
meteorological data comprise air and land surface temperature, relative
humidity, wind speed and direction, shortwave and longwave downwards and
upwards radiation, water vapor pressure, and precipitation on a half-hour
timescale. The active layer data include daily soil temperature and soil
volumetric water content at five different depths. The permafrost data
consist of the ground temperature at 20 different depths up to 28.4 m.
The high-quality and long-term datasets are expected to serve as accurate
forcing data in land surface models and evaluate remote-sensing products for
a broader geoscientific community. The datasets are available from the
National Tibetan Plateau/Third Pole Environment Data Center
