DataRequestWebGUI

Create Custom CMIP6 Data Request

This WebGUI facilitates the use of Martin Juckes'
Data Request Python (DreqPy) API
to generate a customized requested variable list for CMIP6.

A Data Request depends on the MIPs to be supported,
the Experiments to be conducted as well as the
Experiment Tier and the Priority of the requested variables.

In the following a customized data request can be generated
either in .csv or .xlsx format. Alternatively an Excel sheet
containing the data request for all MIPs and Experiments can
be downloaded:

Select DataRequest Version

Select MIP(s)

Select Experiment(s)

Select maximum priority and tier

Variable Priority (max)
Experiment Tier (max)

Generate DataRequest in .CSV format

Select Include for your desired information or - if desired -
alternatively choose a number as sort order priority:
The lower the number, the higher the sort priority.
(Options with setting Include will be ignored in the sorting process!)

   MIP Variable Label
   CMOR Variable Label
   Variable Choice Info
   Standard Name
   Long Name
   Description
   Processing Info
   Cell Methods
   Frequency
   Positive
   Grid
   Dimensions
   Units
   Realm
   Provenance MIP
   Time Slice
   Type
   Variable Priority (lowest value found)
   Experiment Tier (lowest value found)
   MIP Table
   Cell-Measures

Generate DataRequest in .XLSX format

The Excel Sheet will also contain a Data Volume Estimate.
To retrieve a model-specific estimate, the Grid Specification-settings
under the Volume Estimate -Tab have to be adjusted.
Above attribute filters apply only when generating CSV files!

Volume Estimate

In order to perform a Volume Estimate select the MIPs to be supported,
the Experiments to be conducted as well as the maximum Variable-Priority
and Experiment-Tier under the Requested Variables-Tab.
Then adjust below Compression and Grid Specification Settings to your needs:

Compression Ratio

Compression in [%], Integer [1,100].

Grid Specifications

  Ocean: number of horizontal mesh points.

  Ocean: number of vertical levels.

  Atmosphere: number of horizontal mesh points.

  Atmosphere: number of vertical levels.

  Atmosphere: number of vertical levels thereof in stratosphere.

  Atmosphere/Land: number of latitude points.

  Soil: number of vertical levels.

  Force Volume Estimate on the native grid (model grid).

Variable Mapping

Web Application to map a project's CMOR variables to their climate model counterparts.

At first, select a Project. The default project is CMIP6.
In order to edit a model's mapping table, select a Submodel and
click on the Model Icon or the corresponding button labeled Edit.
The Mapping Table files can be generated by
clicking on the button labeled Generate.
Mapping Table Files will be generated for each submodel individually.
In order to request the addition of another project, model or submodel,
please use the Feedback form.

Select Project
