Calculation of Climatology Datasets
Reshapr can be used to calculate climatology datasets from month or day averaged datasets. Here is an example extraction configuration YAML file to calculate the monthly climatology of a collection of physics variables extracted from SalishSeaCast v202111 hindcast.
# `reshapr extract` config to calculate monthly climatology of physics variables
dataset:
model profile: SalishSeaCast-202111-month-avg-salish.yaml
time base: month
variables group: physics tracers
dask cluster: salish_cluster.yaml
start date: 2007-01-01
end date: 2023-08-31
extract variables:
- sossheig
- votemper
- vosaline
- sigma_theta
- e3t
climatology:
group by: month
aggregation: mean
extracted dataset:
name: SalishSeaCast_month_climatology_grid_T
description: Monthly climatology of physics variables extracted from SalishSeaCast v202111 hindcast
dest dir: /results2/SalishSea/month-avg.202111/
The name of the time coordinate in the resulting dataset is month
;
i.e. the value of the group by:
item in the climatology:
stanza.
At present,
the only values accepted for group by:
are month
and day
,
and monthly climatology calculation has been much more thoroughly tested than daily.
A selection:
stanza can be used in conjunction with climatology:
to calculate a climatology
dataset for a subset of the model domain.
climatology:
and resample:
are mutually exclusive.
An error message will be printed if you try to do an extraction with both in the configuration.
