Downloads
New features:
- improved support for netCDF output from WRF model (import time and grid variables)
New operators:
- ydayadd, ydaysub, ydaymul, ydaydiv: Multi-year daily arithmetic
- eca_pd: Precipitation days index per time period
- dv2ps: Divergence and vorticity to velocity potential and stream function
Changed operators:
- import_cmsaf: added time information also for time constant fields
Fixed bugs:
- eof: fix memory access violation
- eofcoeff: fix memory access violation
- fldmean: gives wrong result for grid units [radian]
- Yseasstat: bug fix for datasets with time constant fields
- sellevel: fix problem with hybrid model levels and netCDF output
- sellonlatbox: fix rounding error of the last lon index
- Settime: bug fix for time independent variables in combination with other operators (pipes)
New features:
- Using libtool for linking (rpath)
- Changed predefined gaussian grid names from t<RES>grid to n<N>
Use n80 instead of t106grid to define a Gaussian N80 grid
- Changed percentile parameter type from integer to float
New operators:
- bandpass: Bandpass filtering
- lowpass: Lowpass filtering
- highpass: Highpass filtering
Changed operators:
- eca_gsl: adjust implementation to fit definition by ECA
- expr, exprf: added missing values support
Fixed bugs:
- sellevel: copy zaxis meta data name and units
- seldate: open output file only when time steps found
New features:
- Use NetCDF 4.1.1 instead of Netcdf 4.0.1
- Improved building speed: By using the make variable
MPROCS, the -j options is set during the build process, e.g. make libs4cdo MPROCS=8
will make use of 8 cores. The default value is 2.
- NetCDF and HDF5 are always compiled with PIC support. This improves linking shared libraries against their static versions on some platforms.
New features:
- GRIB1 decode: Correct ZeroShiftError of simple packed spherical harmonics
Fixed bugs:
- wrong result of SZIP compressed GRIB1 records with 24 bit packing and a compression ratio < 1.05
New operators:
- eof: Calculate EOFs in spatial or time space
- eoftime: Calculate EOFs in time space
- eofspatial: Calculate EOFs in spatial space
- eofcoeff: Principal coefficients of EOFs
- consecsum: Consecutive Sum
- consects: Consecutive Timesteps
- setvals: Set list of old values to new values
Using <TAB> in bash, tcsh and zsh can now be used for completion of CDO's options and operators. Cooresponding configuration files for cdo-1.4.4 are downloadable from here or from the repository for the most recent version. This feature will be included in upcoming releases. Use the source command for activation of this feature, e.g. for bash:
source CdoCompletion.bash
Whereas bash and zsh compeltion supports operators with or without leading '-' (operator chaining), tcsh can only complete operators
with prepended '-'.
New operators:
- fldcor: correlation in grid space
- timcor: correlation over time
- gridbox<stat>: computes statistical values over surrounding grid boxes
Changed operators:
- import_binary: added support for variables with different number of levels
- random: added optional parameter 'seed'
Fixed bugs:
- standard deviation: changed the result from missval to zero, if variance is zero
- fldsum: change result from 0 to missval, if only missing values found
- intyear: set the interpolation result always to missval, if missing values found
- Added support for netCDF time bounds
- sellonlatbox: parameter lon2 was not inclusiv
- expr: added support for calculations of const/var
- setday: writes sometimes wrong date information with GRIB result from afterburner
- inputsrv: added level information
- merge: added support to merge levels with datasets in netCDF format
