A dataset of NDVI vulnerability of vegetation affected by drought in Central Asia (1982-2015)

A dataset of NDVI vulnerability of vegetation affected by drought in Central Asia (1982-2015)

The data set includes the start time (year, month), location (longitude and latitude), duration (month), drought intensity and vulnerability data of vegetation response to drought in Central Asia from 1982 to 2015, with a spatial resolution of 1 / 12 °. The drought events were identified by the standardized precipitation evapotranspiration index at the time scale of 12 months (spei12) < - 1.0. The specific algorithm of drought characteristics and vegetation vulnerability is detailed in the citation. The dataset has been applied in the study of vegetation vulnerability to drought in Central Asia, and has application prospects in the research fields of spatial-temporal characteristics of drought events, drought-vegetation interaction mechanism, drought risk assessment and so on.

File naming and required software

File name: the data of drought characteristics and vegetation vulnerability are stored in text format, and the name of the file is " yyyymm.txt ”Where yyyy stands for year and mm stands for month. For example, 200501.txt represents this TXT file, which describes the characteristics of drought events and vegetation vulnerability in Central Asia starting from January 2005.
Data reading mode: all the files in the data set can be opened directly by text program (such as Notepad). The main content is the corresponding information of drought events occurred in the file naming period, and one line corresponds to one drought event. Each row is 8 columns of data separated by commas, from left to right are year, month, grid number, longitude, latitude, drought duration (month), drought intensity (spei) and vegetation vulnerability (NDVI). If you want to display it with a diagram, you can turn it into excel file and open it in ArcMap, with longitude column and latitude column as X field and Y field respectively to display the spatial distribution characteristics of each data.
