climindvis |
Object of type climindvis as returned by |
threshold |
Threshold (numerical). Thresholds need to be provided in mm for precipitation and in degrees C for temperature. |
operator |
One of ">",">=","<","<=" |
thvar |
Variable for which days in range should be calculated (tmin/tmax/tavg/prec) by threshold operator thvar operator2 threshold2 |
iformat |
Format for indicator "perc"(default)/"days" |
NAmaxAgg |
Maximum number of missing values in daily data of each aggregation period (e.g. in all January values for the whole time series). Value between 0 (=0%; no missing values allowed) and 100 (=100%; all values can be missing values). If the number of missing values is higher than NAmaxAgg the index value for the respective grid point/station is set to NA. Default = 20 (20%). |
trend |
Logial (or character). Calculates trends with a predefined method for the chosen index. For information on default method, see |
NAmaxTrend |
Maximum number of years in time series of index which are missing values. Value between 0 (=0%); no years with missing values allowed) and 100 (=100%); all years can be missing values). If exceeded, the trend is set to NA for the respective grid point/station. Note that the value is relative to the length of the time series. Default = 20 (20%). |
