In 2005, another station was operated at the East Rongbuk Glacier Col (28°01′0.95″ N, 86°57′48.4″ E, 6523 m a.s.l.) of Mt. Qomolangma. Observational data from the two sites have been compared with the reanalysis data from the National Centers for Environmental Prediction/National Center for Atmospheric Research (NCEP/NCAR), reliability of NCEP/NCAR reanalysis data has been investigated in the Himalayas/Tibetan Plateau region.

| Abstract: | Due to the difficult logistics in the extreme high elevation regions over the Himalayas and Tibetan Plateau, the observational
meteorological data are very few. In 2003, an automatic weather station was deployed at the northeastern saddle of Mt. Nyainqentanglha
(NQ) (30°24′44.3″N, 90°34′13.1″E, 5850 m a.s.l.), the southern Tibetan Plateau. In 2005, another station was operated at the
East Rongbuk Glacier Col (28°01′0.95″N, 86°57′48.4″E, 6523 m a.s.l.) of Mt. Qomolangma. Observational data from the two sites
have been compared with the reanalysis data from the National Centers for Environmental Prediction/National Center for Atmospheric
Research (NCEP/NCAR), reliability of NCEP/NCAR reanalysis data has been investigated in the Himalayas/Tibetan Plateau region.
The reanalysis data can capture much of the synoptic-scale variability in temperature and pressure, although the reanalysis
values are systematically lower than the observation. Furthermore, most of the variability magnitude is, to some degree, underestimated.
In addition, the weather event extracted from the NCEP/NCAR reanalyzed pressure and temperature prominently appears one day
ahead of the observational data on Mt. Qomolangma, while on Mt. NQ it occurs basically in the same day.
