Southeast Tibet station of Chinese Academy of Sciences: monthly mean temperature data of Ranwu Lake (2014-2020)

This data is mainly the temperature data of the meteorological station set up by the Southeast Tibet station of the Chinese Academy of Sciences in April 2014, located in a ri village, Ranwu Town, Basu County, Changdu City, by the lake in Ranwu, with a geographical location of 96.7699e, 29.4364n and 3920m The model of the instrument probe is hmp155a, the probe is 2m away from the surface, and the underlying surface is alpine meadow. Some original data are missing. It is obtained by correction and interpolation through the flux station also located in the area, the nearby sidaoban meteorological station and the Ranwu station of the Meteorological Bureau. This data is a rare shared data in the region, which can be used as the background basic data of regional climate, rivers, lakes, glaciers, ecology, etc. When using data, the article should reflect the Southeast Tibet station of Chinese Academy of Sciences, and higher precision data can be contacted with the data author.

Moderate resolution MODIS river lake ice cover dataset in high latitude region of northern hemisphere (2002-2018)

The medium-resolution MODIS river and lake ice phenology data set in the high latitudes of the northern hemisphere from 2002 to 2019 is based on the Normalized Difference Snow Index (NDSI) data of the Moderate Resolution Imaging Spectroradiometer(MODIS). Daily lake iceextent and coverage under clear-sky conditions was examined byemploying the conventional SNOWMAP algorithm, and thoseunder cloud cover conditions were re-determined using the temporal and spatial continuity of lake surface conditions througha series of steps.The lake ice phenology information obtained in this dataset was highly consistent with that from passive microwave data at an average correlation coefficient of 0.91 and an RMSE value varying from 0.07 to 0.13.
