Through daily and hourly verification with the observation data of 15 CMA sites and 7 WATER sites, the following conclusions are drawn: 2m surface temperature, surface pressure and relative humidity are relatively reliable, especially 2m surface temperature and surface pressure, the mean error is small and the correlation coefficient is above 0.96;The correlation between the downward short-wave radiation and the observed data at the WATER station was more than 0.9, and the correlation between the downward long-wave radiation was also 0.6.The wind speed of 10m differs greatly from the observed data, and the correlation is weak.The above verification results are for reference only, for specific reference, reference 1 and reference 2. The data of 2014-2015 were updated in April 2016. Data for 2016-2018 were updated in October 2019.

Ground observed precipitation data in Yadong River Valley (2016-2018)

This data set includes precipitation data from a total of nine ground-based precipitation observation stations located in the Yadong River Valley in the middle of the Himalayas. The observation data was collected by the Hobo tumbler rain gauge developed by Onset company and exported through supporting data reading software. Accumulated counts, the rain gauge tipped once, indicating that 0.2 mm of precipitation was recorded, and the default value of -999 was used when no precipitation event occurred. We screened the collected data and eliminated abnormal values to ensure its quality. This data set has made some progress in the analysis of precipitation characteristics, satellite data verification and model simulation evaluation in this area and two academic papers have been published, which provides strong support for the analysis of precipitation characteristics in the high-altitude valleys of the Himalayas lacking ground observation data.

The other observation data are the daily mean value of the measurements taken every half hour. Instrument models of different observations: temperature and humidity: HMP45C air temperature and humidity probe; precipitation: T200-B rain and snow gauge sensor; wind speed and direction: Vaisala 05013 wind speed and direction sensor; net radiation: Kipp Zonen NR01 net radiation sensor; atmospheric pressure: Vaisala PTB210 atmospheric pressure sensor; collector model: CR 1000; acquisition interval: 30 minutes. The data table is processed and quality controlled by a particular person based on observation records. Observations and data acquisition are carried out in strict accordance with the instrument operating specifications, and some data with obvious errors are removed when processing the data table.

Meteorological observation data from the integrated observation and research station of the alpine environment in Southeast Tibet (2007-2017)

This data set includes daily average data of atmospheric temperature, relative humidity, precipitation, wind speed, wind direction, net radiance, and atmospheric pressure from 1 January 2007 to 31 December 2016 derived from the Integrated Observation and Research Station of the Alpine Environment in Southeast Tibet. The data set has been used by students and researchers in the fields of meteorology, atmospheric environment and ecological research. The units of the various meteorological elements are as follows: temperature °C; precipitation mm; relative humidity %; wind speed m/s; wind direction °; net radiance W/m2; pressure hPa; and particulate matter with aerodynamic diameter less than 2.5 μm μg/m3. All the data are the daily averages calculated from the raw observations. Observations and data collection were carried out in strict accordance with the instrument operating specifications and the guidelines published in relevant academic journals; data with obvious errors were eliminated during processing, and null values were used to represent the missing data. In 2015, due to issues related to the age of the observation probe at the station, only the wind speed data for the last 8 months were retained.
