# File Naming Convention:
#

File Naming Convention (if not included above):
    The file naming convention uses the return period of the storm that is
    described in the file, as well as the duration. All surfaces are the
    result of an interpolation of Technical Paper 40 isopluvial maps.

    TP40 + return_period + duration

# Data Description: A data description, dictionary, or codebook
# defines the variables and abbreviations used in a dataset. This
# information can be included in the README file, in a separate
# file, or as part of the data file. If it is in a separate file
# or in the data file, explain where this information is located
# and ensure that it is accessible without specialized software.
# (We recommend using plain text files or tabular plain text CSV
# files exported from spreadsheet software.)
