Hi,
Given the recent ERA update to ERA5.1, i wanted to know if my new MARS request is correct.
Below the parameters I supplied, the only change compared to my earlier script is parameter DATASET which i changed to era5.1
mars - INFO - 20200515.141131 - Processing request 1
RETRIEVE,
DATASET = era5.1,
CLASS = EA,
TYPE = FC,
STREAM = OPER,
EXPVER = 0001,
REPRES = SH,
LEVTYPE = SFC,
PARAM = 40.235/164.128,
DATE = 19991231/20000101/20000102,
TIME = 0600/1800,
STEP = 1/2/3/4/5/6/7/8/9/10/11/12,
DOMAIN = G,
TARGET = "/perm/ms/be/cue/PACKAGE_TOA/data/era5_OLR//ERA5.1_OLR_fc_oper_sfc_20000101_global.grb",
FORMAT = NETCDF,
RESOL = AUTO,
AREA = 89.875/0.125/-89.875/359.875,
GRID = 0.25/0.25
Is that correct in this way?
cheers
Tom

Dear Tom,
access to ERA5.1 data is through the CDS API only using 'reanalysis-era5.1-complete' as per our updated ERA5 complete data download guidelines.
ERA5.1 is a re-run of ERA5, for the years 2000 to 2006 only and is produced to improve upon the cold bias in the lower stratosphere seen in ERA5 during this period.
Cheers
Michela

Hallo Tom,
If you directly use the MARS client to access ER5.1, you should specify expver=51 (with class=ea). Note that the keywords dataset and format are not used with the MARS client. See:
ERA5: data documentation#DataorganisationandhowtodownloadERA5
Keywords in MARS and Dissemination requests
