2030、2050、2100年中国沿海地区气候预估数据集

该数据集是中国沿海地区未来时期（2030-2100年）气温和降水月、季、年尺度的数据集。数据集包括Excel表格数据集和空间栅格数据集。中国沿海地区162个气象站点RCP2.6、RCP4.5和RCP8.5情景下2030-2100年每10年的月、季和年尺度数据。鉴于课题组与国家气象信息中心（中国气象局气象数据中心）已签订气象数据使用的保密协议，因此，Excel表格数据中仅涉及地面气象站点的站号和站名，站点经纬度信息属于保密范畴，未列入Excel表格数据集之中。中国沿海地区RCP2.6、RCP4.5和RCP8.5情景下2030年、2050年和2100年的气温（平均气温、最高气温和最低气温）和降水的空间栅格数据集（Grid和Tiff格式）。空间分辨率为1 km， Albers投影，Datum为Krasovsky_1940。空间栅格数据集命名规则：tmax_2030_26，其中，tmax代表最高气温、2030指2030年、26代表RCP2.6。而tmean、tmin和pre分别代表平均气温、最低气温和降水。

This dataset provides monthly, seasonal, and annual-scale air temperature and precipitation data for coastal China over the period 2030–2100. The dataset consists of two parts: an Excel spreadsheet dataset and a spatial raster dataset.

The Excel spreadsheet dataset contains decadal (every 10 years) monthly, seasonal, and annual-scale data from 162 meteorological stations across coastal China under the RCP2.6, RCP4.5, and RCP8.5 emission scenarios. Due to the confidentiality agreement signed by the research team and the National Meteorological Information Center (Meteorological Data Center of the China Meteorological Administration) regarding the use of meteorological data, the Excel spreadsheet dataset only includes the station IDs and names of the ground meteorological stations, while the station longitude and latitude information, which is classified, is not included in the Excel dataset.

The spatial raster dataset provides air temperature (including mean, maximum, and minimum air temperature) and precipitation data for coastal China in the years 2030, 2050, and 2100 under the RCP2.6, RCP4.5, and RCP8.5 scenarios, available in Grid and TIFF formats. It has a spatial resolution of 1 km, uses the Albers projection, and adopts the Krasovsky_1940 geodetic datum.

The naming convention for the spatial raster dataset is as follows: take "tmax_2030_26" as an example, where "tmax" stands for maximum air temperature, "2030" refers to the year 2030, and "26" represents the RCP2.6 scenario. Similarly, "tmean", "tmin", and "pre" represent mean air temperature, minimum air temperature, and precipitation, respectively.
