mytlc 0.2.0

Python package to download meteorological data and build FAIR datasets.

MYTLC

Package Description

The MYTLC python package is a prototype for downloading meteorological data from multiple sources and building dataset that respect FAIR principles (FAIR Reference). The package depends on the MCAPY package (which is not distributed) to read the content of meteorological files.

Features

Download meteorological data

The following meteorological data can be downloaded with MYTLC :

• ERA5 reanalysis (.nc or .grib) :
  • ERA5 hourly data on single levels from 1940 to present ;
  • ERA5 hourly data on pressure levels from 1940 to present.
• HadISD station observations (complete dataset)

Build dataset

From the downloaded data, MYTLC can build dataset containing :

• All downloaded meteorological data files ;
• A general metadata file ;
• A checksums file (MD5 hash for each meteorological data file) ;
• A content metadata file for each meteorological data file ;
• A release notes file ;
• Additionnal source-dependent files.

MYTLC cannot download data from AROME and ARPEGE models (Météo France) but it can build a dataset if the initial data directory is created manually. The data directory must contain the following elements :

• Meteorological data (.grib or .grib2) ;
• A general metadata file completed manually ;
• A checksums file (MD5 hash for each meteorological data file).

Search dataset

MYTLC allows users to search for files of interest filtered according to following the dimensions :

• Data source ;
• Coordinates (x,y,z) ;
• Time ;
• Weather forecast time ;
• Probabilistic dimension ;
• Meteorological parameters.
