Co-locating¶
The CSO package contains a tool to collect pixels that are co-located with (for example) observaton sites.
Collect co-located pixels¶
The CSO post processing tools could be used to create grid averages.
The configuration of a co-location job looks like:
! single step:
cso.gridded.class : utopya.UtopyaJobStep
! co-location collection task:
cso.gridded.task.class : cso.CSO_CoLocate
cso.gridded.task.args : '${PWD}/rc/settings.rc', \
rcbase='cso.colocate'
The actual work is done by the CSO_CoLocate
class,
see its description for details on the configuration.
The input for co-location is:
a csv table with location information (names, longitudes, and latitudes)
CSO files with pixel data
The result is a set of files with time series of averages over pixels within a distance of the selected locations:
timeseries_202001_daily.nc
timeseries_202002_daily.nc
:
Plot timeseries over co-located pixels¶
The CSO_CoLocatePlotTimeSeries
class could be used
to create plots of time series from the output of the
CSO_CoLocate
class.
The configuration of a co-location job looks like:
! single step:
cso.gridded.class : utopya.UtopyaJobStep
! catalogue creation task:
cso.gridded.task.class : cso.CSO_CoLocatePlotTimeSeries
cso.gridded.task.args : '${PWD}/rc/settings.rc', \
rcbase='cso.colocate-plot'
The following is an example of a timeseries plot that shows averages over co-located pixels with 100 km of a site for at daily and hourly resolution:
