Wind_Speed_Height_Conversion

This program uses the lograithmic wind profile equation(neutral condition) to calculate wind speed at 10m height from the station height. Note: This program should only to be used to convert wind speed over water. For stations over land, pass the roughness length value for land cover types in to the wind_10m.ncl program.

Objective

• To convert wind speed over water from station height to 10m height

Usage

• Two NCL codes are provided:

  • calc_z0_from_ustar.ncl: Estimates roughness length from an array of wind stress.
  • wind_10m.ncl: Main driver. Uses the logarithmic wind equation to calcualte wind at 10m height.

• With proper input file in place, type 'ncl wind_10m.ncl'. This should generate a file with the extensiton input file name+"_10m"

Input file format:

• YYYY MM DD HH WND
