# OpenIFS afterburner (XIFS)

## Background

It should be able to 
* CMORise data, make it CMIP compliant
* Calculate derived variables, e.g. TOA flux, CRF etc
* Interpolate vertical coordinates
* Calculate indices, e.g. ENSO, SOI, NAO etc.
* Automatically plot timeseries of TOA balance, global mean T2m etc.

## Result

A python module that can be loaded in a post processing script or a notebook. 

## How to use GEOMAR cluster

Log in 
```bash
ssh -Y <user>@scalc01.geomar.de
```

Data
```bash
/data/proj/foci/openifs-43r3/OIFS-BJK004/outdata/oifs/
```

Surface data in files
```bash
ECE3_1m_<year>0101_regular_sfc.nc
```
