This SVG image contains embedded raster graphics.[1] Such images are liable to produce inferior results when scaled to different sizes (as well as possibly being very inefficient in file size). If appropriate to do so, they should be replaced with images created using vector graphics. Note: This template is only supposed to be used if the SVG file mixes vector and raster graphics. If the SVG file only contains raster graphics {{FakeSVG}} is supposed to be used. See also {{TopoSVG}}. |
This image is based on CHELSA dataset.
CHELSA datasets are processed with R scripts and visualized with Nasa Panoply.
You must download LGM Chelsa datasets, mean temperature of month 7.

Cutter. Note you must edit this script to take all snampshots from Chelsa datasets.

Metadata
This file contains additional information such as Exif metadata which may have been added by the digital camera, scanner, or software program used to create or digitize it. If the file has been modified from its original state, some details such as the timestamp may not fully reflect those of the original file. The timestamp is only as accurate as the clock in the camera, and it may be completely wrong.
