Scripts to get and process ERA5 and ECMWF data for MSS on Linux

CDS-API

Setup

1. Create an account at https://cds.climate.copernicus.eu/user/register
   Log into your account
2. Navigate to https://cds.climate.copernicus.eu/api-how-to#install-the-cds-api-key
   Copy the content of the upper black box to the right and paste it into ~/.cdsapirc
3. Accept https://cds.climate.copernicus.eu/cdsapp/#!/terms/licence-to-use-copernicus-products

Scripts Setup

1. Clone this repository and change into it

   git clone https://github.com/Open-MSS/data-retrieval.git
   cd data-retrieval
   

2. Create an environment and install all requirements

   pip install -r requirements.txt
   

3. Make sure cdo and nco are installed
   e.g. for Ubuntu/Debian

   sudo apt-get install cdo nco netcdf-bin
   

4. Adjust the settings.config to your liking (copy from settings.example)

Usage

1. After completing both setups, you can use this script as follows:

   ./bin/get_cds.sh <date> <time>
   

   For example, to get ERA5 data for March 2nd 2020 at 12 o'clock, use

   ./bin/get_cds.sh 2020-03-02 12:00:00
   

2. Done, copy the .nc files to your mss data directory and give them their appropriate suffix.
   Using the demodata for MSS, this is ~/mss/testdata and EUR_LL015 suffix.

   for file in ./mss/*.nc; do mv "$file" "${file/.nc/.EUR_LL015.nc}"; done
   mv ./mss/*.nc ~/mss/testdata
