Module contents

class cmaqsatproc.readers.omps.OMPS_NPP_L2[source]

Bases: satellite

Default OMPS satellite processor.

classmethod open_dataset(path, bbox=None, **kwargs)[source]
Parameters:

  • path (str) – Path to a OMPS L2 OpenDAP-style file

  • bbox (iterable) – swlon, swlat, nelon, nelat in decimal degrees East and North of 0, 0

  • kwargs (mappable) – Passed to xarray.open_dataset

Returns:

sat – Satellite processing instance

Return type:

OMPS_NPP_L2

classmethod prep_dataset(ds, bbox=None, path=None)[source]

Defines valid based on Latitude/Longitude and bbox, and inteprolates pixel centers to corners.

Parameters:

  • ds (xarray.Dataset) – Satellite dataset

  • bbox (iterable) – swlon, swlat, nelon, nelat in decimal degrees East and North

  • path (str) – Unused.

Returns:

ds

Return type:

xarray.Dataset

class cmaqsatproc.readers.omps.OMPS_NPP_NMNO2_L2[source]

Bases: OMPS_NPP_L2

Default OMPS NO2 satellite processor. * valid when

  • GroundPixelQualityFlags == 0

  • PixelQualityFlags == 0

Thin wrapper around satellite.cmr_links where concept_id is set to “C1386443916-GES_DISC”.

Parameters:

method (str) – ‘opendap’, ‘download’, or ‘s3’.

Returns:

links – List of links for download or OpenDAP

Return type:

list

classmethod prep_dataset(ds, bbox=None, path=None)[source]

Defines valid based on Latitude/Longitude and bbox, and inteprolates pixel centers to corners. Then further subsets valid pixels where GroundPixel and Pixel QualityFlags are 0.

Parameters:

  • ds (xarray.Dataset) – Satellite dataset

  • bbox (iterable) – swlon, swlat, nelon, nelat in decimal degrees East and North

  • path (str) – Unused.

Returns:

ds

Return type:

xarray.Dataset

class cmaqsatproc.readers.omps.OMPS_NPP_NMTO3_L2[source]

Bases: OMPS_NPP_L2

Default OMPS O3 satellite processor. * valid when

  • GroundPixelQualityFlags == 0

  • QualityFlags == 0

Thin wrapper around satellite.cmr_links where concept_id is set to “C1386443916-GES_DISC”.

Parameters:

method (str) – ‘opendap’, ‘download’, or ‘s3’.

Returns:

links – List of links for download or OpenDAP

Return type:

list

classmethod prep_dataset(ds, bbox=None, path=None)[source]

Defines valid based on Latitude/Longitude and bbox, and inteprolates pixel centers to corners. Then further subsets valid pixels where GroundPixelQualityFlags and QualityFlags are 0.

Parameters:

  • ds (xarray.Dataset) – Satellite dataset

  • bbox (iterable) – swlon, swlat, nelon, nelat in decimal degrees East and North

  • path (str) – Unused.

Returns:

ds

Return type:
