The code for handling COPY directives was very old and quite different from the code for handling KEEP or EXCLUDE directives. It has been re-written to follow the same principles as KEEP/EXCLUDE.

Some code restructuring (moving a method from AllSkyLW_Generator to TauCLDGenerator) so the TAU_CLD generator can now generate solar index values by comparing the measured ISWR to the potential radiation. Moreover, when using a CLD parameter, it must now be between 0 and 8 instead of 0 and 1.

The SMET plugin was not consistent with the specification: when no time zone was provided, it should have assume tz=0 but it used the Input::Time_Zone value instead. This has been changed so it properly follows the specification: no time zone -> gmt. When writing data out, the time zone will now always be written.

The STD_PRESS spatial interpolation algorithm has been extended and can now deal with multiple input stations (with 2 different methods for handling this case). The Imis plugin now reads the air pressure and convert it to station air pressure (instead of sea level). Otherwise, improved error messages in libsmet and documentation / minor code cleanup.

A new method for the spatial interpolations of ISWR has been implemented. Helper methods have been implemented in SunObject and DEMObject (possibility to reset the altitude without recomputing the whole solar position, horizon computation from one point toward a given direction). 
The smet_extract script now writes its output to stdout instead of to a file since the previous behavior was mostly an anoyance...

A little bit of includes cleanup, code cleanup in Sun.cc and added the atmospheric corrections logic (from Alpine3D) to the Sun object so it can easily be reused.

A new parameter ENABLE_RESAMPLING has been added in the [Interpolations1D] section. It is now possible to globally turn resampling off...

The MERGE feature was still quite buggy, this should now work much better (ie properly handling the "extra" parameters). A warning has been fixed in libsmet. Better handling of julian_date in smet_extract (converting to ISO timestamp in the output).

The "<" and ">" operators have been defined for MeteoData in order to make it easier to sort vectors of MeteoData. The FULL_MERGE merging strategy has been implemented alongside with some code cleanup/restructuring and some code optimizations.

When merging data from different stations, it is now possible to specify (with the Input::MERGE_STRATEGY key) how the merge should be done. The FULL_MERGE is currently not implemented.

An error message when a smet file misses its epsg ocde and/or altitude as been improved. The MERGE example has been improved in order to be clearer. A bug in the append mode of smet files has been fixed (possibility of a duplicate timestamp).

Now the last timestamp in a SMET file can be compared to the data that should be appended in order to decide if the file should be truncated or not

This is the first version of an append feature for SMET files. Not all the case might be well handled but at least, it starts to work... (with more optimizations to come)

Better error handling for the GSN plugin as well as forcing the station_id to lowercase when building the URL (so instead of a cryptic GSN error message, it just works)

Last changes to support the Cray compiler. Please note that for Cray, you most probably have to compile with static linking!

Trying to make the CMakeLists clearer and more modular: the compiler options are now set through a macro that will be shared with the other projects. New targets appeared: Intel and Cray, but this is still a work in progress.

Handling some warnings for new version of clang in MathOptim.h (turning them off for the bit manipulations). Laying the foundations for the append mode in SMET files (not usable yet).

Fixed two warnings on osX and turned off the global-constructor / exit-time-destructor warnings for Clang (since there is pretty much no viable alternative to what these warnings are about). Fixed a formatting typo in smet_extract.sh

The possibility of monthly aggregation (AVG, MIN, MAX) has been added as well as support for julian timestamps

Now even files with JULIAN timestamps can be restricted to certain time ranges (provided as ISO formatted time string)

First fixes for NetCDF so it could be used by Alpine3D: a bug when handling precipitation grids has been fixed (nodata now remain nodata) and the data packing has been removed (since when appending new grids it can simply not work). A future alternative could be "bit shaving", see https://www.unidata.ucar.edu/blogs/developer/entry/compression_by_bit_shaving .

Documentation improvements, fixed a bug when generating kml files (wrong altitude appended to the name), improved the layout when using smet_range and trying to convert average values to sums in GRIBIO for easier further processing.

An unpleasant bug has been fixed in data_converter when handling large number of stations and time ranges. Minor code cleanup in some plugins.

Cleaning up the docuemntation: the PREVAH landuse code are only of interest for Alpine3D so this has been moved into its documentation

A new tool has been contributed by Aurélien Gallice: a Python class to read SMET files. The smet2kml script now adds the altitude to the station name, making it more convenient when plotting names on a map.

Some docuemntation has been written in the PSUDistribute code to help with debuging *for next time*. The Accumulate resampling now fills the first nodata with 0 (since we know that we don't have enough information to re-accumulate at the first point). The unused "isGzip" booleans have been removed from the smet code since this is currently not supported the way we want it.

A new script has been created to help select SMET files based on the parameters they contain. A bug has been found in PSUMDistribute when a distribution interval would be followed by a large data gap (it was filling the remaining of the buffer with 0).
