Data from: Vegetation on the move: Elevational shifts and greening dynamics across the Himalayan alpine zone

This dataset contains processed climate and vegetation data supporting
analyses of spatiotemporal vegetation dynamics from 1999 to 2022 across
six study regions in the Himalayas. The dataset is organized into four
components: (1) annual climatic variables derived from ERA5 reanalysis
data, including total precipitation (TP), skin temperature (SKT), and snow
depth (SD); (2) pixel-level Normalized Difference Vegetation Index (NDVI)
values extracted from Landsat imagery, along with derived trend metrics
(initial NDVI, linear trend slope, and statistical significance); (3)
annual estimates of vegetation line elevation derived using the Triangle
method; and (4) regionally aggregated summary metrics integrating climate
variables, vegetation trends, and elevational changes. The data enable
assessment of relationships between climate variability, vegetation
greenness, and elevational shifts, and can be reused for comparative
studies of vegetation–climate interactions. All variables are provided in
standardized formats and units as described in the associated manuscript.
Missing values are indicated as NA. The dataset contains no personal or
sensitive information and is suitable for open access distribution. No
ethical restrictions apply. Code used for data processing and analysis is
available from the corresponding author upon reasonable request.
