Dear WRF Community,
I am trying to run WRF using ERA-Interim as boundary condition. However, when downloading data, I have met a problem. I used three separated grib files for WPS processing.
ERA-Invariant.grib
ERA-SFC-201503.grib
ERA-ML-201503.grib
When downloading Model Level Variables ERA-ML-201503.grib, I used the following script:
#!/usr/bin/env python
from ecmwfapi import ECMWFDataServer
server = ECMWFDataServer()
server.retrieve({
"class": "ei",
"dataset": "interim",
"date": "2015-03-01/to/2015-03-30",
"expver": "1",
"grid": "0.75/0.75",
"levelist": "1/2/3/4/5/6/7/8/9/10/11/12/13/14/15/16/17/18/19/20/21/22/23/24/25/26/27/28/29/30/31/32/33/34/35/36/37/38/39/40/41/42/43/44/45/46/47/48/49/50/51/52/53/54/55/56/57/58/59/60",
"levtype": "ml",
"param": "130.128/131.128/132.128/133.128",
"step": "0",
"stream": "oper",
"time": "00:00:00/06:00:00/12:00:00/18:00:00",
"type": "an",
"target": "ERA-ML-201503.grib",
})
It accounts ~6.5G for ERA-ML-201503.grib, and this script fails to download a whole year since the output is a very large file.
My question is: it is necessary to download such a large file? How to adopt the above script for downloading ERA-ML (only WRF run purpose)?
