The default ilwr model in Atmosphere as been changed to Unsworth. The fixed snow albedo has been set to 0.85 for all filters/generators using it. 

The Config class can now import an ini file from another ini file, this could greatly simplify the management of operational deployments (a station that has a special configuration now can simply import a standard config file and redefine what it needs). This is either done with IMPORT_BEFORE or IMPORT_AFTER in order to choose who has precedence. Multiple (ie recursive) inclusions are supported with some enforced limitations to prevent circular dependencies.

The graphical message box for exceptions has been turned off by default, because it was interfering with cdash. Packagers are therefore invited to turn it ON for public packages (since this tends to make users read the error messages).

A major bug has been found in the potential short wave solar radiation calculation: the beam values were actually already projected to the horizontal, leading to a double projection to horizontal when requesting the horizontal components. The whole potential radiation code has been reviewed, comparing line by line with Iqbal. A few variables have been renamed in order to better match the paper. And more detailed comments added to explain some of the most mysterious parameters. The potential ISWR data generator has been adjusted and checked. it can use a measured ILWR to correct for cloudiness if available.

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

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 user provided cloudiness can now be forced to the ILWR models (if not nodata). The selection of which model to use based on the available parameters has been improved and verified.

A new method for getting the parametrized ILWR has been implemented that chose between various parametrizations depending on the available data. The data_converter example has been slightly edited for clarity.

Fixed a warning with XCode 4.3 on osX. Tried to make a more standard use of c++ (relying on std::fill for filling vectors, relying on vector.resize(sixe, value) instead of manually initializing a vector, etc). A few more const added where appropriate. It makes the benchmarks slightly faster...

Added the wind log scaling law. Code cleanup in GRIBIO as well as more meteofileds supported. The readDEM method has been implemented.

Another fix/enhancement for POPC: the libraries now ends with "popc" in the popc version, as the autotools build was doing.

Windchill and heat index have been implemented in Atmosphere.

Some cleanup in the filters, some code moved to ProcessingBlock, so that elements that are not filters can inherit ProcessingBlock and get all that it needs. A processing element has been implemented to multiply by a given constant, another one to add a given offset and another one to correct precipitation for undercatch.

Some invalid doxygen comments have been fixed in MathOptim.

Some variable names starting with "_" have been fixed. The Crawford and Duchon ILWR model has been implemented in Atmosphere and checked on Weissflujoch data.

A bug was fixed in SMETIO: when given OLWR, it should have computed TSS, but it was not... (using the wrong MeteoData object).

Documentation and error messages improvements. A new method was added to Atmosphere: virtualTemperatureFactor.

Several HACKS have been removed (either the HACK had been fixed but the comment was still there, or it has now been fixed, or after more (careful) consideration, it has been decided that the HACK was not a HACK)

The emissivity models have been cleaned up: they now take RH, TA, etc but NOT the water vapor pressure (it is internally calculated). Please, update your code!

A specific spatial interpolation algorithm has been introduced for ILWR that relies on emissivity (we convert ILWR to emissivity, then interpolate the emissivity, then reconvert to ILWR). As mentionned in issue 156, a better method for interpolations by proxies will have to be designed and implemented...

The arrays are now using the vector filling methods when possible. A specialized template for convertString(unsigned int) has been written. 

A two segments linear fit (for elevation detrending) has been implemented with a fixed inflection point. This is quite primitive but allows the LLIDW spatial interpolation to use it and therefore to behave like the traditional SLF SnowFit program. More work will be needed for fully configurable regression algorithm choice though... 

Some namming issues have been fixed in COSMOXML. A better emissivity handling has been implemented in SNIO to be closer to the original Snowpack (ie: compute clear sky ILWR when no cloudiness/emissivity is given).

A few functions have been added to the Atmosphere class that are usefull (specifically for Alpine3D snowdrift)

More meteo laws have been implemented, alongside new constants. An extra check has been added for the USER spatial interpolation algorithm.

The full support for timezones has been brought back. This fixes issue 71. The SMET, SMET, IMIS, BORMA plugins have been validated. Geotop should be validtaed if an input data set is available. A new class will have to be implemented to represent time periods. This is currently only a typedef pointing to the Date class, but a specific class would be welcomed.

GSN has been fixed for some changes on the web service, but does not retrieve the correct timestamps (is this a GSN issue?). The GSN compilation has been improved: the warnings related to GSOAP have been removed. 

A new long wave radiaiton model using cloudiness as input has been added (Omstedt, 1990). 

A new group of classes has been created, under the meteolaws subdirectory. This contains various general meteorological laws, such as a sun radiation model, standard atmosphere, etc

The first implementation (not tested yet) of a non-linear least square fit algorithm has been implemented in the libfit1D. 

Several documentation issues have been fixed (obsolete code examples, etc) and classes grouped by modules. This should help the user to quickly locate the classes of interest.
