1) Data content (including elements and significance): 19 stations (South-East Tibetan station, Namucuo station, Qomolangma station, Medog station, Ngari station, Naqu station（ITPCAS）, Golmud station, Tianshan station, Qilianshan station, Ruoergai station(NIEER) , Yulong Xueshan station, Naqu station(NIEER), Haibei Station, Sanjiangyuan station, Shenzha station, Ruoergai station (CIB), Naqu station(IG SNRR), Lhasa station，Qinghai lake station) Meteorological observation data sets (temperature, precipitation, wind direction and wind speed, relative humidity, atmospheric pressure, radiation and evaporation) of the Qinghai Tibet Plateau in 2019 2) Data source and processing method: field observation excel format of 19 stations in Alpine network 3) Data quality description: Daily resolution of stations 4) Achievements and prospects of data application: Based on the long-term observation data of the field stations in the alpine network and the overseas stations in the pan third polar region, a series of data sets of meteorological, hydrological and ecological elements in the pan third polar region are established; through the intensive observation and sample plot verification in key areas, the meteorological elements, lake water and water quality, aboveground vegetation biomass, glacier and frozen soil changes are completed According to the inversion of products; based on the technology of Internet of things, the meteorological, hydrological and ecological data management platform with multi station networking is developed to realize real-time acquisition, remote control and sharing of online data.
Pollen and spores extracted from sediment are considered as the important proxy in reconstructing past vegetation and climate, and which plays essential role in investigating environmental evolution during the Quaternary. Accurate identification of pollen and spore is the base for palynological research, which determines it is quite necessary to establish modern atlas for pollen and spore. Supported by the projects the Strategic Priority Research Program of Chinese Academy of Sciences “Pan-Third Pole Environment Study for a Green Silk Road (Pan-TPE)” and The Second Tibetan Plateau Scientific Expedition and Research, authors completed the vegetation and soil surveys in 2018 for the alpine meadow in the east Tibetan Plateau (including Yushu Prefecture, Changdu City, Ganzi prefecture, Naqu City) and alpine forest in the southeast Tibetan Plateau (Linzhi City) , and collected 401 specimens for anther of flowering plants and sporangium of ferns. Pollen and spores were extracted and from these specimens using the standard acid-alkali approach and acetolysis (9:1 mixture of acetic anhydride and sulphuric acid) treatment, and further were refrigerated in glycerin. More than two photographs were took for each pollen and spore type, using the LEICA-dm-2500 optical microscope and its imaging system with scale. The atlas of pollen and spore morphology will be a valuable reference for palynology research and teaching.
