  • 全球长序列高分辨率光合有效辐射(PAR)(1984-2018)

    Photosynthetically active radiation (PAR) is fundamental physiological variable driving the process of material and energy exchange, and is indispensable for researches in ecological and agricultural fields. In this study, we produced a 35-year (1984-2018) high-resolution (3 h, 10 km) global grided PAR dataset with an effective physical-based PAR model. The main inputs were cloud optical depth from the latest International Satellite Cloud Climatology Project (ISCCP) H-series cloud products, the routine variables (water vapor, surface pressure and ozone) from the ERA5 reanalysis data, aerosol from the Modern-Era Retrospective analysis for Research and Applications, Version 2 (MERRA-2) products and albedo from Moderate Resolution Imaging Spectroradiometer (MODIS) product after 2000 and CLARRA-2 product before 2000. The grided PAR products were evaluated against surface observations measured at seven experimental stations of the SURFace RADiation budget network (SURFRAD), 42 experimental stations of the National Ecological Observatory Network (NEON), and 38 experimental stations of the Chinese Ecosystem Research Network (CERN). The instantaneous PAR was validated at the SURFRAD and NEON, and the mean bias errors (MBEs) and root mean square errors (RMSEs) are 5.6 W m-2 and 44.3 W m-2, and 5.9 W m-2 and 45.5 W m-2, respectively, and correlation coefficients (R) are both 0.94 at 10 km scale. When averaged to 30 km, the errors were obviously reduced with RMSEs decreasing to 36.3 W m-2 and 36.3 W m-2 and R both increasing to 0.96. The daily PAR was validated at the SURFRAD, NEON and CERN, and the RMSEs were 13.2 W m-2, 13.1 W m-2 and 19.6 W m-2, respectively at 10 km scale. The RMSEs were slightly reduced to 11.2 W m-2, 11.6 W m-2, and 18.6 W m-2 when upscaled to 30 km. Comparison with the other well-known global satellite-based PAR product of the Earth's Radiant Energy System (CERES) reveals that our PAR product was a more accurate dataset with higher resolution than the CRERS. Our grided PAR dataset would contribute to the ecological simulation and food yield assessment in the future.

  • 亚洲水塔区域陆地蒸散量长期数据集(1982-2018)

    Evapotranspiration (ET) is an very important water balance component for the “Asia water tower”, Tibetan Plateau (TP). However, accurately monitoring and understanding the spatial and temporal variability of ET components (soil evaporation-Es, canopy transpiration-Ec, and intercepted water evaporation-Ew) over the TP remains very difficult, due to the scarcity of observational data for this remote area. Here, the 37 years (1982-2018) monthly ET components on the TP were produced using the MOD16-STM model, which uses the recently available datasets of soil properties, meteorological conditions, and remote sensing. The estimated ET correlates very well with measurements from 9 flux towers, with low root mean square errors (RMSE=13.48 mm/month) and mean bias (MB=2.85 mm/month), and the coefficient of determination (R2=0.83) and the index of agreement (IOA=0.92). The annual averaged ET for the whole TP (specified with an elevation higher than 2500m) is about 0.93±0.037 Gt/year. The main contribution of ET on the TP comes from the soil, with Es accounted for more than 84% of ET. The ET showed a significantly increasing trend with rates of about 1 to 4 mm/year (p<0.05) over most parts of the central and eastern TP, while a significantly decreasing trend with rates of -3 to -1 mm/year was shown in the northwestern TP. The increasing rate of ET in TP over the past 37 years is around 0.96 mm/year. The increase in ET over the entire TP from 1982 to 2018 can be explained by warming and wetting during the same period. MOD16-STM ET exhibited acceptable performance at TP, which was demonstrated by comparison with previous studies. It can adequately represent the actual ET and can be used in research on water resources management, drought monitoring, and ecological change, for example.

  • 青藏高原北麓河气象冻土地温监测数据集(2017-2018)

    Frozen soil refers to a soil or rock mass with a temperature lower than or equal to 0 ° C and containing ice. It is particularly sensitive to temperature and its physical and mechanical properties change significantly with temperature. The frost heaving deformation and melt settlement deformation of frozen soil are the most common frozen soil disasters. Their occurrence is mainly caused by the change of the inherent temperature of frozen soil due to the frozen soil engineering activities. Therefore, the protection of frozen soil is mainly to protect the temperature of frozen soil. , to maintain it in the closest state before the engineering activities. The main method for obtaining the temperature of the frozen land is to embed the temperature measuring cable. Through the data acquisition function of the CR3000, the resistance value of the temperature measuring cable is obtained at different times, and the temperature value is calculated by the correspondence between the calibration coefficient and the resistance value. According to the sensitive characteristics of frozen soil to temperature, the change of ground temperature can reflect the change of climate, and can also analyze the influence mechanism and degree of human activities on the stability of frozen soil in combination with other factors, so as to guide the later engineering activities. Upgrading and upgrading of frozen soil protection measures.
