Anchor flexpart_filter flexpart_filter
fieldset flexpart_filter(...)
Extract fields from FLEXPART output GRIB files. This function uses this set of keyword arguments:
source
The FLEXPART output GRIB file.
data
The FLEXPART output GRIB as a fieldset. It takes precedence over source.
param
The shortName of the parameter to extract.
levType
The type of level to extract. The possible values are: "hl" and "sfc". The default is "hl".
level
The level to extract.
step
The forecast step to extract.
release
The release to extract. Release indexing starts at 1.
ageclass
The ageclass to extract. Ageclass indexing starts at 1.
Example:
# to read parameter mdc (mass density concentration) for level 5000 m
, for all the timesteps, releases and ageclasses
g=flexpart_filter(source: "my_flexpart_output.grib",param: "mdc",level: 5000)
Anchor flexpart_total_column flexpart_total_column
fieldset flexpart_total_column(...)
Computes the sum/vertical integral of fields in a FLEXPART output GRIB file. This function uses this set of keyword arguments:
source
The FLEXPART output GRIB file.
data
The FLEXPART output GRIB as a fieldset. It takes precedence over source
param
The shortname of the GRIB parameter. If param is "mdc" (mass density concentration) the column integrated mass is computed. Otherwise the fields are simply added up for the specified level range.
top_level
The top height level (inclusive) for the computations. Optional.
bottom_level
The bottom height level (inclusive) for the computations. Optional.
step
The forecast step to extract.
release
The release to extract. Release indexing starts at 1.
ageclass
The ageclass to extract. Ageclass indexing starts at 1.
Example:
# to
compute the total column integrated mass for all the steps, releases and ageclasses
g=flexpart_total_column(source: "my_flexpart_output.grib")
