This function generates daily climatological maps.
daily_clima(b, dates = NULL, verbose = FALSE)
RasterBrick/Stack containing the historical observations or a proxy
(typically a reanalysis) that is used to derive the climatological
information. This needs to contain daily layers for multiple years.
b@z
should contain dates for comparison
(e.g. 2017.01.01).
Dates for which we need to calculate daily climatology. By default, this is a leap year.
Logical defining whether message should be printed on screen (FALSE by default).
The function returns a RasterBrick (if dates
contains one date)
or a list of RasterBricks (if dates
contains more than one date).
Extent, resolution and land-sea mask match those of b
.
Values are the subset of b
related to the given dates
.
the climatology is calculated over the period spanning 4 days before and
