Data Archive and Access -The files in the dataset are compressed and named as YYYYV.tar.gz where YYYY stands for the year, and V for variable name. For example, the file 2000w.tar.gz is a compressed file, saving all of the information of wind speed in the year 2000. -After you decompress the YYYYV.tar.gz, there will be 2920 ( or 2928 for leap years) binary files for each year, named as YYYYMMDD_HHhr_V.bin where YYYY stands for the year, MM for the month, DD for the day, HH for the hour and V for the variable name. For example, the file 20000101_0hr_w.bin stores the wind speed information of 2000-1-1 0 a.m (GMT). for Mainland China, and it is a binary file. -Each binary file, YYYYMMDD_HHhr_V.bin, contains 370210 data with the type of short[int]( 2 bytes). And the values are expanded by 10 or 100 times( see the scaling factors in the download table) from the original values, so you should devide the data by the corresponding scaling factors before you use them. We also provide a Fortran program( described below) to convert the binary file to ordinary readable file( with the surfix of .dat). -For the geographic_infortion about the 370210 values in each decompressed file, please refer to the geographic_information.dat described below. Other files in this directory - geographic_information.dat£ºThis file contains 370210 lines and 4 columns. The first column is the indentification number, the second column is the latitude of the point, the third column is the longitude and the final column is the elevation of the each corresponding point. - technical_details.pdf: This file contains the introduction about the building of this dataset, including the methods, data and analysis of results. -format-conversion.f90: This file helps to convert the decompressed binary file to ordinary file( with the surfix of .dat). And the use of this program has been demenstrated in the file.
