List of all the 2D variables hosted in DKRZ and those incorporated into XCES
The data can be found under /work/bmx828/miklip-ces/data4miklip/reanalysis/reanalysis/era5. The raw format of this data is hosted in DKRZ under /pool/data/ERA5.
The 2D variables may belong to 2 different data types:
| data type | characteristics | meaning |
|---|---|---|
sf00 | surface vars | pure analysis (no forecast), only intensive data (e.g. temp). |
sf12 | forecast & accumulated | forecast starting at 06:00, extensive data (e.g. precip). Instantaneous: valid at the time indicated by time+step (e.g. 06:00 +1h i.e. at 07:00) Accumulated: aggregation between step and step+1 (the steps are of 1 hour) |

Some variables may be found in more than one type, in these cases we set a default source (bolded), although that can be changed as per user request.
The information contained in the table is the following one:
| column | meaning |
|---|---|
| XCES_VAR | variable name at XCES |
| EC_VAR | original variable name from ECMWF, more info at ECMWF's Parameter Database |
| XCES_STD_NAME | standard name at XCES |
| XES_LONG_NAME | long name at XCES |
| VAR_NO | ECMWF variable number, more info at ECMWF's Parameter Database |
| XCES_UNITS | variable units at XCES |
| PROCESS | the variable can be I (instantaneous), A (accumulated), EX, EI (max., min.) I variables go from 00-23 at each day. A, EX, EI variables go from 01-00 at each day. |
| AVAIL_TYPES | available datatypes at DKRZ (in bolded the ingested one) |
| INCLUDED | YES/(NO) |
