How to download the Tco319L137 (about 32 km) resolution data of ECMWF S2S (subseasonal to seasonal)?

Datasets and Usage

Hi - I download the subseasonal forecast data from the website ECMWF | S2S, ECMWF, Reforecasts, Daily averaged through a Python script (an example is as follows).

#!/usr/bin/env python
from ecmwfapi import ECMWFDataServer

server = ECMWFDataServer()
#!/usr/bin/env python
from ecmwfapi import ECMWFDataServer

server = ECMWFDataServer()

server.retrieve({
“class”: “s2”,
“dataset”: “s2s”,
“date”: “2023 - 01 - 02”,
“expver”: “prod”,
“hdate”: “2022 - 01 - 02”,
“levtype”: “sfc”,
“model”: “glob”,
“origin”: “ecmf”,
“param”: “165”,
“step”: “0/to/1104/by/6”,
“stream”: “enfh”,
“time”: “00:00:00”,
“type”: “cf”,
“format”: “netcdf”,
“target”: “U10_hdate_2022_01_02.nc”
})

Using the above script, the default resolution is 1.5 degrees. However, in the S2S documentation, it is mentioned that the resolution of the CY48R1 model version is Tco319L137 (about 32 km). May I ask:

  1. If I modify the script and add the statement ‘grid’: ‘0.32/0.32’, is the downloaded result automatically interpolated by the platform instead of the original Tco319L137 (about 32 km)?
  2. Then, how to download the original official reforecast and real-time forecast data of Tco319L137 (about 32 km)?

Thank you～～
