1. Introduction

This page provides a data catalogue of the parameters provided as part of the DestinE Climate DT data portfolio.

This data can be retrieved using the polytope service via the DestinE Service Platform, with examples on usage here.

Some key facts:

Temporal resolution:
- Hourly atmospheric fields
- Daily mean ocean fields
Spatial resolution:
- resolution=high → HEALPIX H1024 or H512 depending on the simulation.
- resolution=standard → HEALPIX H128.

Data is provided on various levtype values, for different parameters. The levtype values are as follows:

hl : Height level field. The key levelist is used to specify the level in metres (e.g. 100). For parameters at height > 10m.
o2d : 2D ocean field. Note that this can be the ocean surface, or other 2D levels such as at 2 metres or total column integrations.
o3d : 3D ocean field. The key levelist is used to specify the index of the level. Technical details of these levels can be found here for ICON and here for IFS-NEMO.
pl : Pressure level field. The key levelist is used to specify the level in hPa (e.g. 1000).
sfc : 2D atmospheric surface field. Note that this can be the earth surface, or other 2D levels such as at 2 metres or total column integrations
sol : 3D multi-level model field. This encompasses fields from soil, sea-ice and snow model which use multi-layer schemes. The key levelist is used to specify the index of the level.

For example, retrieve future projection (SSP3-7.0) data, parameters "Surface pressure" (param 134) and "2 metre temperature" (param 167), on 2nd January 2020 at times 0000 to 0600 every hour:

request = {
    'class': 'd1',
    'dataset': 'climate-dt',
    'activity': 'ScenarioMIP',
    'experiment': 'SSP3-7.0',
    'expver': '0001',
    'model': 'IFS-NEMO', 
    'generation': '1',
    'realization': '1',
    'resolution': 'high', 
    'date': '20200102',
    'time': '0000/0100/0200/0300/0400/0500/0600',
    'stream': 'clte',
    'type': 'fc',
    'levtype': 'sfc',
    'param': '134/167'
}

Modifying the request can then be performed based on the available output parameters and data layout as detailed below. You can find more examples on usage here.
