Climate Tools (Series Homogenization and Derived Products)

Functions for the quality control, homogenization and missing data infilling of climatological series and to obtain climatological summaries and grids from the results. Also functions to draw wind-roses and Walter&Lieth climate diagrams.



Date Version Changes

04-May-2018 3.1.1 Checking that station codes are not duplicated and do not include the '-' symbol. Important bug correction.

15-Apr-2018 3.1 New file conversion functions daily2climatol(), rclimdex2climatol and climatol2rclimdex(). New function datsubset() to subset data into new input files. Bug correction in homogsplit(). Bigger labels in graphics.

27-Aug-2016 3.0 Many novelties, with new functions (to prepare the input data from ODBC accessible data bases, to obtain grids from the homogenized series, etc) and new functionalities added to others. The package is now able to deal with daily data, and can honor stations metadata. (Be aware that some parameters change their names to be more mnemonic).

01-Nov-2013 2.2.1 Bug fixed: a global color re-assignment resulted in abnormal halt under most O.S.+latest R combination.

01-Oct-2013 2.2 Code optimization allows the process to be completed in around half the time of the previous version. Original series can be labeled as homogeneous to keep them unchanged. Some parameters have more meaningful names (the old are kept for backward compatibility), and a couple default values have been changed. dahstat() has a new option to yield the homogenized series in individual text files. A map is drawn in the station location figure if the package 'maps' is installed.

05-Jun-2011 2.1 Corrected bugs in distance and trend computations and an improved convergence in the missing data recomputation yiel much better homogenization results.

25-Jan-2011 2.0 Too many to explain here. The main novelty is the homogen() function, for an automated homogenization of climatological series. Other functions have been changed or replaced, so you cannot expect compatibility with the 1.x versions.

06-Oct-2006 1.0.3 Change of '�C' by just 'C' to avoid non-ascii characters warnings in the R checking process of the package, and update of the PDF poster of the documentation.

26-May-2006 1.0.2 Minor corrections in the documentation and workaround to avoid 'Error: NAs are not allowed in subscripted assignments', produced when using option sqrtrans=TRUE in function depudm() since R version 2.0.0.

01-Nov-2004 1.0 First public release.
