Description
This data is Standardized precipitation evapotranspiration index (SPEI) for different time scales from 851 to 2000. The time scale is partially omitted due to the upload capacity, but it is from 1 month to 48 months at maximum.
[Structure]
Spatial resolution: 1.9(Treated the earth as a 94x192 grid)
Time resolution: 1 month(1150 year = 13800 month)
This data is one-dimensional. When using, please slice to (13800,94,192) using python, etc.
The method for obtaining the grid for the survey area is as follows.
north latitude: (94/180)*(90+lat)
south latitude: (94/180)*(90-lat)
east longitude: (192/360)*longitude
west longitude: (192/360)*(360-longitude)
This SPEI is calculated using the SPEI package in R. The settings for this package are as follows.
Setting
kernel: type = rectangular, shift =0
distribution: log-Logistic
fit: ub-pwm
The data used for this SPEI calculation are climate data reconstructed by data assimilation using isotope ratios. Please refer to the following page for details of the data.
