Dear users,

we're upgrading the Redmine system (code.mpimet.mpg.de) during an extraordinary maintenance on Tuesday, 16th of April.

• os-upgrade on this Redmine system (https://code.mpimet.mpg.de)

• Tuesday, April 16th, 8.30 am - 10 am

• Redmine (https://code.mpimet.mpg.de) will be unavailable for about 1 hour

• Changed to C++20
• Add FDB (Fields DataBase) support (status: experimental)
• Remapweights: Use environment variable REMAP_MAP3D=1 to generate all mapfiles of the first 3D field with varying masks
• pack: add support to read pack parameters from file
• select: allow negative numbers for parameter levidx to select level indices from the end

• pressure - pressure on full-levels
• pressure_half - pressure on half-levels
• delta_pressure - pressure difference of half-levels
• gheight_half - geopotential height on half-levels

• after: change computation of geopotential height from full to half levels [Bug #11346]
• expr: var statement failed
• gradsdes: fix integer overflow in map file
• Arith: fill mode for infile2 doesn't work with pipes [Bug #11733]
• rotated pole mapping failed with negative north_pole_grid_longitude attribute [Bug #11661]

• Add experimental interface to FDB5
• Add global option CDI_Threadsafe to lock non thread-safe netCDF4/HDF5 calls

• improve support for time units second [Bug #11740]
• calc_chunk_cache_size: wrong result for 3D data (bug fix)
• netCDF: write of y-coordinates failed for Gaussian reduced grids (bug fix)

New features:

• Add GRIB2 HEALPix support (available with eccodes-2.32.0)
• Add support for NetCDF attribute type NC_INT64
• Add interface function streamInqNumSteps() to inquire number of time steps
• gribapi decode: add support for single precision float interface (available since ecCodes-2.30.0)
• grib2: add read only support for alternativeRowScanning
• grib2: add support for earth radius specified by data producer

Fixed bugs:

• HIRLAM_EXTENSIONS: set default CDI_KEY_SCANNINGMODE to 64 [Bug #11367]
• gribapiDefGridLCC: store DxInMetres/DyInMetres as double
• NetCDF4: use chunkSize only if it is less than gridsize
• cdfDefineAttributes: check filetype for unsigned int attributes
• time information missing if the stream contains fields constant in time only

New features:

• Add option --shuffle: Specify shuffling of variable data bytes before compression (NetCDF)
• packed NetCDF arrays are stored unpacked for all operators which modify the data
• DCW regions: add support for states (e.g. dcw:USAK for Alaska)
• expr: added function gridindex() (grid cell indices)
• expr: add function cdoy() (day of year) and cdpy() (days per year)

New operators:

• gridcellindex: Get grid cell index from lon/lat point
• timfillmiss: Temporal filling of missing values
• vertfillmiss: Vertical filling of missing values
• Add module Ymoncomp - Multi-year monthly comparison (operators: ymoneq ymonne ymonle ymonlt ymonge ymongt)

Changed operators:

• remapscon: obsolete operator, use remapcon instead
• remapcon2: rename to remapscon2
• gencon2: rename to genscon2

Fixed bugs:

• expr: internal functions with two constant arguments failed in release 2.2.1
