title: A dataset of monthly temperature vegetation dryness index along the China–Pakistan Economic Corridor from 2000 – 2017
title: 中巴经济走廊2000–2017年逐月温度植被干旱指数数据集

description: Drought disasters happen frequently along the China–Pakistan Economic Corridor (CPEC), which restrict the development and safety of the alongside countries. Therefore, we need to conduct the research of drought monitoring along the CPEC. Soil water content (SWC) is a fundamental indicator to predict drought. Temperature vegetation dryness index (TVDI) could predict drought by inverting surface soil water content. This dataset is based on normalized differential vegetation index (NDVI) and land surface temperature (LST) from MODIS, combined with SRTM DEM data and applied NDVI-LST spatial characteristics to get the monthly TVDI by extracting the spatial edge of dryness and wetness along CPEC from 2000-2017. The study area is from 41°25'24.49"N to 23°45'24.49"N and from 60°53'57.97"E to 79°52'27.97"E. The data format is GeoTiff with the spatial resolution of 1 km. According to the precipitation and soil water content from the meteorological stations, the correlation analysis showed that TVDI had a significantly negative correlation with SPI and SWC (p&lt;0.001). Our result could support drought monitoring and prediction along CPEC

title: A dataset of Ya'an Earthquake based on social media
title: 雅安地震灾情的社交媒体数据集

description: The Ya'an Earthquake occurred on April 20, 2013 in Beijing time. It was located in Lushan County, Ya'an City, Sichuan Province, and the magnitude of this earthquake was 7.0. As of 14:30 on the 24th, the earthquake caused a total of 196 people dead, 21 missing and 11470 injured. With the development of information and communication technology，based on previous research, we find that micro-blog system had shown great potential in promoting emergency response because they provided an easily accessible information platform on which disaster information could be rapidly organized and shared to a large number of people. Based on this, taking the Ya'an Earthquake as an example, this dataset was collected the Sina-Weibo data of Sichuan Province after 7 days of the Ya'an Earthquake. Sina-Weibo, a platform for information sharing and exchanging for entertainment and leisure life services for the general public, was launched in August 2009. Sina-Weibo can be used by users to search, inquire and publish post-earthquake-related blog. The public can communicate on Sina-Weibo, express their feelings, and can also provide some better suggestions and other functions.

title: Inverted land surface temperature for Sanya city based on Landsat data
title: 基于Landsat数据的三亚市陆表温度反演数据集

description: This study uses Landsat series image data to construct a radiative transfer model, with which to carry out ground surface temperature inversion in Sanya city. Based on the radiative transfer model, land surface temperature was inverted by means of atmospheric profile parameter calculation, visible light band processing, and surface emissivity calculation. As such, the surface temperature products of Sanya city in 2000, 2004, 2008, 2012, 2016 and 2018 were experimentally obtained. Once optimized, this research model can be extended to a wide range of cities, thereby acquiring high application value.

title: A dataset of actual evapotranspiration and water use efficiency of typical terrestrial ecosystems in China (2000–2010)
title: 2000–2010年中国典型陆地生态系统实际蒸散量和水分利用效率数据集

description: Evapotranspiration (ET) is the central process and major component within terrestrial hydrological cycle and energy balance, and water use efficiency (WUE) represents the coupling between carbon and water cycles. Both ET and WUE have been widely used in the researches of ecology, agriculture, hydrologyand climatology. Eddy covariance (EC) method is regarded as the only standard method directly measuring the material and energy exchanges between biosphere and atmosphere, which is the most important method for GPP and ET observations at the ecosystem scale. By synthesizing eddy-covariance carbon and water flux observations in China from both ChinaFLUX sites and published literature, we constructed the actual evapotranspiration and water use efficiency dataset of typical terrestrial ecosystems in China. The dataset contains 143 records of annual actual ET and 96 records of annual mean water use efficiency from 45 ecosystems across china during 2000 - 2010. This dataset could provide data support for analyses on terrestrial carbon and water cycles, ecosystem management and evaluation, global change and other related researches.

title: A dataset of lake ice phenology in Qinghai Lake from 2000 to 2018
title: 2000～2018年青海湖湖冰物候特征数据集

description: Lake ice phenology is considered a sensitive indicator of regional climate change. Qinghai Lake is the largest saltwater lake in China. Its lake ice phenological characters and changes have attracted much attention. Based on remote sensing datasets including the MOD09GQ surface reflectance product and Landsat TM/ETM+/OLI images, a dataset of lake ice phenology in Qinghai Lake from 2000 to 2018 was built by using RS and GIS technologies. Due to spectral differences between lake ice and lake water, the method of threshold segmentation was adopted to extract the ice area of Qinghai Lake based on MOD09GQ product, which was achieved by setting a reflectance threshold for red band and a reflectance difference threshold between red and near-infrared bands. The extracted ice area was then validated against the visually interpreted ice area based on Landsat TM/ETM+/OLI images, which showed a relative error of 0.8％ only. This dataset includes ice-water vector boundary data, area ratio, and phenological characters in Qinghai Lake from 2000 to 2018. Specifically, phenological information records the start and end dates of lake freeze-up and break-up, freeze-up periods, etc. This dataset provides an important reference for exploring the spatio-temporal characteristics of lake ice in Qinghai Lake, as well as for formulating responses of lake ice-based climate changes in the region.

Then assisted by high-resolution remote sensing images and Google Earth images to verify the classification accuracy. Results show a Kappa coefficient of 84.67%，85.98%，80.61%，88.66% and 90.66% for the subsets, respectively, demonstrating a high accuracy of the classification results. This dataset can be directly used to study the spatial and temporal distribution of land surface water. It also provides data basis for water environment research, such as water body studies and water resource safety assessment.

description: As a big agricultural country, China has experienced a series of natural disasters such as the Great Famine, the 1998 floods and the 2008 snow storm since the founding of the People’s Republic of China. We present a dataset summarizing the affected area, disaster area and the area of total crop failure at provincial level in China, with a temporal coverage from 1949 to 2015. Based on the agricultural planting structure and natural disaster data, data of grain disaster loss are also presented through a grain loss assessment model. The dataset plays an important role in the prediction, prevention and reduction of agricultural disasters in future.
