1-km monthly precipitation dataset for China (1901-2020)

1-km monthly precipitation dataset for China (1901-2020)

This dataset includes the monthly precipitation data with 0.0083333 arc degree (~1km) for China from Jan 1901 to Dec 2020. The data form belongs to NETCDF, namely .nc file. The unit of the data is 0.1 mm. The dataset was spatially downscaled from CRU TS v4.02 with WorldClim datasets based on Delta downscaling method. The dataset was evaluated by 496 national weather stations across China, and the evaluation indicated that the downscaled dataset is reliable for the investigations related to climate change across China. The dataset covers the main land area of China, including Hong Kong, Macao and Taiwan regions, and excluding islands and reefs in South China Sea.

File naming and required software

2019qzkk0603-zgyjsl: in which, 2019QZKK is the project number, 06 represents task 6,03 represents topic 3, and zgyjsl is the initial letter of Chinese pinyin;The data format is NETCDF, nc data can be opened by ArcMAP software;Matlab can be used for extraction and processing, Matlab released the function to read and store the nc file, the reading function is ncread, switch to the nc file storage folder, the statement is expressed as: ncread (' XXX. Nc ', 'var', [I j t], [leni lenj lenj]), where XXX.Var is the name of the variable read from XXX. Nc.I, j and t are respectively the beginning row, column and time of data reading, while leni, lenj and lent I are respectively the length of data reading in the dimension of row, column and time.Thus, this function can be used to read any region and any time period in the study area.
