1.12

📅 2020-10-29

• The csv output of 'harpdump --dataset' can now be used as content of a .pth
  file. This improves the performance of harpcollocate/harpmerge/etc. as they
  no longer need to open and extract metadata from files themselves anymore.

• harpcollocate now stores differences as signed values in collocation result
  file (instead of absolute differences).

• Added harp_dataset_prefilter(). This function is now also called within
  harpmerge and harpcollocate to pre-filter the input dataset(s) for datetime
  and collocate left/right filters that are at the start of the operations
  string.

• Added format and history fields to harp_product_metadata.

• Added harp.import_product_metadata() to Python interface.

• harp_dataset_add_product() now ignores files/directories starting with '.'.

• Added uncertainty propagation to bin() and bin_spatial() operations
  (using uncorrelated assumption for bin() and correlated for bin_spatial()).

• Added global option to determine whether uncertainty propagation should
  use a correlated or uncorrelated approach. Currently only used for the bin()
  operation.

• Added global option to create a collocation_datetime variable when performing
  a collocate_left() or collocate_right() operation.

• Added wildcard pattern matching ('*'/'?') to keep() and exclude() operations.

• Added derivation to retrieve angstrom exponent from aerosol optical depth.

• Added derivation to retrieve tropospheric/stratospheric column avk from
  total column avk and tropopause altitude.

• Fixed potential memory issues and improved overall code stability.

• Updates to product ingestions:

  • S5P L2 CLOUD: added cloud_type and cloud_top_temperature
  • S5P L2 O3: added qa_filter=custom ingestion option to set validity based
    on official PRF recommendation for processor V1.x generated products

    validity flag mapping to version 4.x-4.0 of the Data Quality document

1.11

📅 2020-05-19

• Added derivations to retrieve column number density from column vmr.

• Fixed issue in bin_spatial() where the weightfactor could be too high when
  oversampling the input data. Grid cells that intersected with the data
  polygon could end up with a weightfactor >1.0 (but <2.0).

• Fixed issue where molar mass was incorrectly provided for the species with
  the shortest matching name. e.g. the molar mass of CO was returned for CO2
  and of NO for NO2. This impacts vmr <-> mmr conversions for BrO2, COF2, COS,
  CO2, C2H2O2, H2O2, NOCl, NO2, N2O, N2O5, and all isotopologues (e.g. H2O_161).

• Removed irrelevant harp_str64() and harp_str64u() functions (HARP does not
  support 64bit integers).

• Fixed issue where molar mass linked to variables with a 'surface',
  'tropospheric', or 'stratospheric' prefix returned 0.

• Fixed error/crash in deriving dry air column vmr from dry air column mmr.

• Updates to product ingestions:

  • GOME-2 L2: added support for SO2 columns at all plume heights
  • OMI L2 CLDO2/CLDRR: added validity variable

1.10

📅 2020-03-31

  for reduce_operations parameter in harp.import_product() Python function.

• Fixed incorrect "invalid variable" error on weight variables for angular
  quantities when performing a harpmerge.

• Fixed issue where the udunits2 library could not be initialized if the
  environment had a LC_NUMERIC locale that did not have '.' as decimal
  separator.

• Fixed issue in name mangling of embedded expat library.

• Updates to product ingestions:

  • GOMOS L1 Limb: fixed unit of wavelength_photon_radiance (and uncertainty)
    and documented conversion algorithm
  • S5P L2 O3 PR: support for IODD 12.0.0
  • S5P L2 O3 TPR: removed support (future availability of product uncertain)
  • GEOMS PANDORA: allow for trailing \0 in global attribute values

1.9.2

📅 2019-12-01

  • Calipso L2: fixed unit of backscatter coefficient

1.9.1

📅 2019-11-01

  pressure were a factor 10 too low.

• Fixed issue where operation following an index filter operation did not
  get executed.
