RELEASE HISTORY OF THE airGR PACKAGE
3
4
5
6 
#### 1.0.5.12 RELEASE NOTES (2017-01-23) ###########################
7
8 
- Bug fixed in DataAltiExtrapolation_Valery(). The elevation gradients for air temperature returned by CreateInputsModel() are improved.
9
10 
- DataAltiExtrapolation_Valery() and CreateInputsModel() now present a PrecipScale argument which allows rescaling precipitation when it is interpolated on the elevation layers when CemaNeige is used.
11
12 
- DataAltiExtrapolation_Valery() has been improved. DataAltiExtrapolation_Valery() now runs faster (and by consequence CreateInputsModel() too when CemaNeige is used).
13
14
15 
#### 1.0.4 RELEASE NOTES (2017-01-18) ###########################
16
17 
- RunModel_CemaNeige(), RunModel_CemaNeigeGR4J(), RunModel_CemaNeigeGR5J() and RunModel_CemaNeigeGR6J() now return air temperature for each elevation layer.
18
19 
- S3 plot method defined for OutputsModel objects. It means that the plot_OutputsModel() function is deprecated and his use has been replaced by the use of plot.OutputsModel() or plot().
20
21 
- In plot.OutputsModel() the PlotChoice argument is deprecated and has been renamed "which".
22
23 
- plot.OutputsModel() displays air temperature time series for each layer when CemaNeige is used (argument which = "Temp" or "all").
24
25
26 
#### 1.0.3 RELEASE NOTES (2016-12-09) ###########################
27
28 
- Bug fixed when StartParamList or StartParamDistrib arguments are used in the CreateCalibOptions() function.
29
30 
- CreateInputsModel() now returns an error if NLayers <= 0 when CemaNeige is used.
31
32 
- plot_OutputsModel() now displays raw values on the y-axis when the discharge time series is represented with log scale (formerly, log values of discharges were displayed on the y-axis).
33
34 
- ErrorCrit*() functions gain a warnings argument to replace the verbose action and the verbose argument now prints the criterion value(s).
35
36
37 
#### 1.0.2 RELEASE NOTES (2016-11-03) ###########################
38
39 
- The RunModel_GR6J() and RunModel_CemaNeigeGR6J() models were modified back to versions previous to 1.0.1 to prevent from unwanted efficiency criteria deterioration related to the calibration with Calibration_Michel().
40 
  The actual model codes were not modified but the TransfoParam_GR6J() and CreateCalibOptions() functions were modified regarding the X5 parameter.
41 
  It is strongly advised to use airGR 1.0.2 for the RunModel_GR6J() and RunModel_CemaNeigeGR6J() functions if you are using Calibration_Michel(), as they are much more efficient.
42 
  In case you were using your own calibration algorithm, you will not notice any difference.
43
44 
- The value "sort" for the transfo argument of CreateInputsCrit() was not taken into account. It is now fixed.
45
46 
- SeriesAggreg() gains a TimeLag argument that corresponds to a numeric value indicating a time lag (in seconds) for the time series aggregation (useful to aggregate hourly time series to the daily time step for instance).
47 
  In addition, the function now accepts input dates in both POSIXt formats (POSIXct and POSIXlt). The output is in POSIXct format.
48
49 
- CreateInputsModel() and DataAltiExtrapolation_Valery() functions now allow both POSIXt formats (POSIXct and POSIXlt).
50
51 
- plot_OutputsModel() gains a log_scale argument in order to plot the flow with a log scale.
52
53 
- CreateCalibOptions() loses the OptimParam argument that was redundant with the FixedParam argument. Calibration_Michel() was modified to take into account this change by using directly FixedParam, but this is transparent to the user.
54
55 
- CreateCalibOptions() loses the StartParam argument that was not used.
56
57 
- A tutorial is available online on the following link: from http://webgr.irstea.fr/airGR.
58 
  It can also be displayed with the vignette("airGR") command

#### 1.0.1 RELEASE NOTES (2016-04-21) ###########################
62
63 
- The GR5J model has been modified: previously, two unit hydrographs were used, now only one is remaining.
64 
  As a consequence, simulations from the GR5J (RunModel_GR5J() function) and CemaNeige (RunModel_CemaNeigeGR5J() function) models will be different.
65
66 
- An important proportion of the transformations of the parameters have been modified (TransfoParam*() functions). Since this modifies the local search, calibration results will be different .
67
68 
- The quantiles of the parameters have been recalculated with the new transformations (CreateCalibOptions() function). Since these quantiles constitute the starting point of the calibration algorithm, calibration results will be different.
69
70 
- The Calibration_HBAN() and DataAltiExtrapolation_HBAN() functions have respectively been renamed as Calibration_Michel() and DataAltiExtrapolation_Valery() after the names of their creators.
