PINT is now properly supported in SMET. The OLWR/TSS conversion must now be handled by a data generator (implemented as "TS_OLWR"). A bug in the Coords documentation has been fixed.

The plugins are now handled by an object factory, removing the need for the IOPlugin class. Otherwise, small documentation update in GeneratorAlgorithms.

better file structure: all the classes purely focused on data storage (such as grids, dates, etc) have been moved into a "dataClasses" directory. All subdirectories are nhow named similarly to the classes and methods: the words after the first one are capitalized.

Fixed a documentation issue in GeneratorAlgorithms, fixed a warning in config.dox and wrote some documentation for the PSQL plugin. Some cleanup also took place in the PSQL plugin.

A new pre-processor variable has been defined: MSVC so the pragmas for VC++ are now properly enabled for msvc only. An improper include for MSWIN has been removed.

The WIN32 pre-processor variable has been renamed in MSWIN since this is more logical on Win64 (and to avoid potential conflicts). Some headers have been cleaned up in the process (in Timer.h/.cc). A new method has been moved from Config to FileUtils: isAbsolutePath. Some extra features (support for offset in hours) added to NetCDFIO.

The Winstral spatial interpolation algorithm is getting into shape: all three modes of operation have been implemented and tested and it is now properly documented. A new data generator has been created that computes a relative humidity from either a dew point temperature or a specific humidity.  Adding a "check_attribute" to libncpp.

More refinements to the Winstral spatial interpolation: it is now possible to provide a reference station to take the wind direction from, or to provide a fixed wind direction. 

Data Creators have been defined: it is now possible to create an extra parameter from a data generator. Simply define it as {param_name}::create = {generators} in the [Generators] section and the parameter will be created from any data generators specified (beside the "create" syntax, everything is currently identical with data generators).

The Idso clear sky ILWR has been added (and also added to the clear sky generator). Some (dead) code that was committed by mistake has been removed and the very begining of what will be needed for data creators put in place (still some way to go!).

The ClearSky and AllSky generators have been renamed as ClearSky_LW and AllSky_LW for clarity. The debug outputs (.toString()) have been improved. The Config::findKey method is now able to do pattern matching anywhere in the string (if "anywhere=true"). This makes some code simpler (for generators). 

The parameter copy feature has a new syntax: TA2::COPY = TA will copy TA into TA2 (clearer and more consistent). Please update your ini files if necessary!

Two extra clear sky parametrizations have been added, including one for desert conditions. They are available to the ClearSky generator. Small code and documentation cleanup.

Finally, the AllSky data generator is in good shape. It properly caches the previous valid cloudiness value for each station, a bug in the cloudiness calculation has been found (for low sun angles)and the documentation is now in order. We just need to get a cloudiness parameter in MeteoData in order to also be able to read measured cloudiness!

More improvements to the AllSky data generator: it now computes the cloudiness if none is provided. Another improvement will have to be brought for working with multiple stations as well as adding the cloud fraction to the MeteoData parameters! (ie: stay tuned!)

Since the number of clear or all sky parametrizations seem to multiply, two generic generators have been implemented: clearsky and allsky that take as argument which parametrization to use. Therefore the old Brutsaert or Dilley have been removed. The Unsworth should follow at some point, after we will have added the cloud fraction as a meteo parameter and found a way to also specifiy a parametrization for clear_sky_index <-> cloudiness that could be used by the all sky generators.

Moving code around in Atmosphere (to keep the clear sky parametrizations together).

Added a Dilley clear sky generator. The Unsworth does not provide clear sky as a fallback anymore, this has to be configured by the user (so the user can choose which fallback to enable).

The two arguments accumulate resampling algorithm has been removed. The distribute filter should be used instead. The missing files are now committed.

A little more cleanup (constification, mostly) in GSNIO as well as documentation. Updated the example io.ini. And a new data generator: Brutsaert for clear sky ILWR.

Two new undercatch corrections have been implemented: for the Chinese Standard Precipitation Gauge and for the shielded Geonor gauge.

A documentation bug has been fixed in GeneratorAlgorithms. Some warnings and white spaces have been fixed in GeneratorAlgorithms.

Finally! Handling precipitation redistribution before re-accumulation (ie the 24 hours sums provided in an otherwise hourly data file) now works with non-uniform timesteps. This introduced some runtime performance hit (~10% slower) but better accomodate the needs of our users!

Finally, it is now posible to handle precipitation data provided as 24 hours sums in an hourly data file and resample them as 15 minutes sums. The limitations are: no time offset between the requested sampling period and the measured accumulation period; only constant sampling in the data file (ie no variations in the sampling period in the data file).

The filters have been slightly simplified, some IOUtils functions optimized (after reading an interesting post about the handling of rvalues), a bug fixed in PNGIO on Windows, the macros MAX and MIN are not used anymore (relying on std::max and std::min instead). A new data generator is on its way to generate HNW from HS differences (but this will require architectural changes to the DataGenerator).

Fixing some warnings for Visual C++ and also using ostringstream instead of stringstream when appropriate

A stupid bug has been fixed in SMETIO: the OSWR was not renamed as RSWR anymore. Otherwise, small documentation fixes.

Fixed the license file (issue 309), updated the documentation to include the SIN generator and fixed a wrong commit of the example io.ini

The exceptions were not printed with a line return anymore, messing up the display. A function to extract the integral and the fractional part of a double has been added. The julian day number calculation (ie how many days since the begining of the year) was numericaly instable (leading to wrong values in an unpredictable way). A data generator that can generate sinusoidal values (for daily or yearly periods) has been added. The potential radiation generator can now handle missing TA and/or RH (of course, reverting to a very simplistic clear sky model, assuming an average reduced precipitable water).

The Unsworth parametrization for ILWR has been fixed and now works as data generator. Some comments have been added to Sun.cc.

Some code cleanup and micro-optimizations. The documentation has been improved (configuration of doxygen as well as some duplicate section labels).

Fixed a stupid bug in Unsworth generator (it was always generating data...), improved the documentation of POT_RADIATION and tried to play with a cloudiness factor (not working yet).

A new generator for ISWR or RSWR has been implemented, providing clear sky, potential radiation. Overall, writing the code and its documentation and testing it took less than half an hour!

A buf in some unsworth implementation in Atmosphere has been fixed (check with nodata). The order of the meteodata fields has been changed because this directly impacts the order of the processing of the fields (the goal being that fields that are often checked with a combination of other fields get processed in the end).

The unsworth_dilley ILWR data generator has been implemented with the usage of the last cloudiness during the night as well as the usage of a generic snow albedo (or grass albedo) to convert RSWR to ISWR (if necessary) coupled with a threshold on the snow height.

The METEO_TIMSERIES and STATION_TIMESERIES have been renamed in METEO_SET and STATIONS_SET in order to better reflect their content. 

The concept of data generators is introduced. A new section has been created [Generators] to define how to generate data for each parameter when everything else failed. Soon, you will be able to generate ILWR directly by declaring it in your io.ini!
