Gets the last day in a temperature time series, expressed as decimal julian days since 1970-1-1 00:00 UTC

Calculates the covariance matrix of the normally standardized variables obtained from the columns of x

TemperatureStartDay

Gets the first day in a temperature time series, expressed as decimal julian days since 1970-1-1 00:00 UTC

months REPLACEMANT

PrecipitationEndDay

Gets the last day in a precipitation time series, expressed in decimal julian days since 1970-1-1 00:00 UTC

ComprehensiveTemperatureGenerator

The Comprehensive Temperature Generator

Plots the auto- and cross- covariance functions between measured and simulated data for several stations

ComprehensivePrecipitationGenerator

PrecipitationStartDay

Gets the first day in a precipitation time series, expressed in decimal julian days since 1970-1-1 00:00 UTC

RMAWGEN-package

R - Multi-site Autoregressive WEather Generator

Gets the toponym where a meteorological station is located

continuity_ratio

Calculates the continuity ratio of a set of precipitation measured or generated data in several sites as defined by Wilks, 1998 (see reference link)

inv_GPCA_iteration

This function makes an inverse iteration of PCA-Gaussianization process

serial.test function for varest2 object

normalizeGaussian_severalstations_prec

DEPRECATED Converts several samples x random variable (daily precipitation values) extracted by populations represented by the columns of data respectively or sample to a normally-distributed samples with assinged mean and standard deviation or vice versa in case inverse is TRUE using the function normalizeGaussian_prec

counts NAs in each row of data

plotDailyClimate

Plots daily climatology through one year

is.monthly.climate

Verifies if 'climate' represents the monthly climatology in one year, i.e 'climate' is monthly.climate type matrix whose rows represent months and each column represents a station. It is also used in setComprehensiveTemperatureGeneratorParameters.

newVARmultieventRealization

Generates several realizations of a VAR model

Extracts the elements of a data frame corresponding to a period between year_min and year_max for the stations listed in station

normalizeGaussian_prec

Converts precipitation values to "Gaussinized" normally-distributed values taking into account the probability of no precipitation occurrences. values or vice versa in case inverse is TRUE

forecastResidual

Forecasts the residual value of a VAR realization given the white noise covariance matrix

generateTemperatureTimeseries

Returns time series of Daily Maximum and Minimum with a random multi-realization obtained by using newVARmultieventRealization. This function is called by ComprehensiveTemperatureGenerator.

extractTxFromAnomalies

Extracts generated time series of Daily Maximum Temperature from a random multi-realization obtained by generateTemperatureTimeseries function
