IceCast (version 2.1.0)

read_monthly_BS: Read in a set of bootstrap observations over a set of year

Description

Function to process monthly bootstrap data over multiple years. The observations are from the monthly sea ice concentration obtained from the National Aeronautics and Space Administration (NASA) satellites Nimbus-7 SMMR and DMSP SSM/I-SSMIS and processed by the bootstrap algorithm. The resultsare distributed by the National Snow and Ice Data Center (NSIDC) (Comiso 2017). Functions assume file name conventions are the same as used by NSIDC.

Usage

read_monthly_BS(start_year, end_year, file_folder, version, nX = 304,
  nY = 448)

Arguments

start_year

first year to read in

end_year

last year to read in

file_folder

folder in which binary files are stored

version

either 2 or 3 indicating which version of the bootstrap data you are using

nX

longitude dimension

nY

latitude dimension

Value

bootstrap observations sorted into array of dimension: year x month x lon x lat

Details

raw binary files for 2012-2013 are included in the package as an example

Examples

# NOT RUN {
#my_file_path should be a file path where the 1983 binary files are stored
observed_demo <- read_monthly_BS(start_year = 1983, end_year = 1983,
                             file_folder = my_file_path)
# }
