Globsim

About

Globsim helps you to download reanalysis data from ERA-Interim, MERRA2, and JRA-55 for a target area and to interpolate it to point time series for individual locations (here called 'stations'). This is intended to replace or supplement meteorological observations in remote areas. This page provides high-level information that is required as an entry point to using Globsim. All python code is documented with comment and (doxypyppy?). The sub-directory examples/ contains examples of relevant control files.

Directories and files

Globsim weeks with three differing directories. The source directory is what is contained in this GitHub repository (default: ~/src/globsim). The credentials directory is where your login credential files for the differing reanalyses are found (default: ~/.). The target directory is the location to which data is downloaded and where processed data is found.

Credentials directory

Contains credentials files with login information, see directory examples/.

 .ecmwfapirc  (ERA-Interim credentials)
 .merrarc     (MERRA2 credentials)
 .jra55rc     (JRA-55 credentials)
