MDG625: Meteorological Dataset with 0.0625° resolution produced by GeoAN

MDG625: Meteorological Dataset with 0.0625° resolution produced by GeoANThe meteorological data sets of parts of Asia from 1940-2016 produced by deep learning methods GeoAN with geopotential-guided attention.More information can refer [github](https://github.com/songzijiang/GeoAN).The file names and directory structure are organized in the following format:```[file_split].tar/geoan-[file_index]-[variable_name].tif```> [file_index] is the number of days elapsed since 1940-1-1. A table of index and date correspondences is available in ’idx.txt‘.> [file_split] is calculated by [file_index]//100, e.g. 0.tar contains the data of 0-99 (from 1940-1-1 to 1940-04-10).> [variable_name] can be chosen from ['PRS', 'TMP', 'WIN'], which represent surface pressure, the temperature at 2m, and wind speed at 10m, respectively.## change list:V3: produced from a new pre-trained model to improve the performance of the dataset, the first day of the dataset is changed to 1940-1-1.V2: change author information and title.V1: init commit.
