classmethod PSLClimateIndices.StringsToArcGISTable(strings, table, fields, overwriteExisting=False)

Creates and populates a table of climate index values parsed from a list of strings, where each string is the data for a single climate index in NOAA PSL time series format.

Requires: ArcGIS Pro 3.2.0 or later or ArcGIS Server equivalent to ArcGIS Pro 3.2.0 or later.

Parameters:

• strings (list of str) –

  List of one or more multi-line strings in the PSL time series format documented at https://psl.noaa.gov/data/climateindices/list/:

  year1 yearN
  year1 janval febval marval aprval mayval junval julval augval sepval octval decval
  year2 janval febval marval aprval mayval junval julval augval sepval octval decval
  ...
  yearN janval febval marval aprval mayval junval julval augval sepval octval decval

  For example, the North Atlantic Oscillation (NAO), available at https://psl.noaa.gov/data/correlation/nao.data, looked like this (circa 2007):

  1948 2007
  1948 -99.90 -99.90 -99.90 -99.90 -99.90 -99.90 -99.90 -99.90 -99.90 -99.90 -99.90 -99.90
  1949 -99.90 -99.90 -99.90 -99.90 -99.90 -99.90 -99.90 -99.90 -99.90 -99.90 -99.90 -99.90

  You should provide the entire text above as one string in the input list, the entire text for a different climate index as the second string, and so on.

  Any lines following missing_value are treated as comments.

  Minimum length꞉ 1.

• table (str) –

  Table to create and populate. The table will have at least four fields:

  • IndexDate (DATE) - the date of the first day of the month and year of the climate index value (e.g. 1-March-1960).

  • IndexYear (LONG) - the year of the climate index value (e.g. 1990).

  • IndexMonth (LONG) - the month of the climate index value, ranging from 1 to 12.

  • Value (DOUBLE) - the index value for that month and year. There will be one of these fields created for each climate index that you provide as inputs. The names of these field are specified by the Climate Index Value Fields parameter. If the output table is a dBASE table (a DBF file), the missing_value parsed from the input data will be used to represent “no data is available”. For other types of tables, a database NULL will represent “no data is available”.

  The second two fields store the same data as the first field but are present for your convenience, in case you prefer the year and month broken out as integers.

  The rows will be inserted in ascending date order and all 12 months will be included for every year. If these months occur in the future they will have the missing_value or NULL as described above.

  Minimum length꞉ 1.

• fields (list of str) – Names of the fields to receive the climate index values. You must provide a field name for each climate index you provide as input. Minimum length꞉ 1.

• overwriteExisting (bool, optional) – If True, the output table will be overwritten, if it exists. If False, a ValueError will be raised if the output table exists.
