First ISCCP Regional Experiment (FIRE) Cirrus 2 National Oceanic and Atmospheric Administration (NOAA) Wind Profiler Langley DAAC Data Set Document |
|
The First ISCCP Regional Experiments have been designed to improve data products and cloud/radiation parameterizations used in general circulation models (GCMS). Specifically, the goals of FIRE are (1) to improve the basic understanding of the interaction of physical processes in determining life cycles of cirrus and marine stratocumulus systems and the radiative properties of these clouds during their life cycles and (2) to investigate the interrelationships between the ISCCP data, GCM parameterizations, and higher space and time resolution cloud data.
To-date, four intensive field-observation periods were planned and executed: a cirrus IFO (October 13 - November 2, 1986); a marine stratocumulus IFO off the southwestern coast of California (June 29-July 20, 1987) a second cirrus IFO in southeastern Kansas (November 13 - December 7, 1991); and a second marine stratocumulus IFO in the eastern North Atlantic Ocean (June 1 - June 28, 1992). Each mission combined coordinated satellite, airborne, and surface observations with modeling studies to investigate the cloud properties and physical processes of the cloud system.
This document provides information for the FIRE_CI2_NOAA_WNDPFS data set.

The NOAA wind profiles were collected during the period from Nov. 13, 1991 to Dec. 7 1991. The original data were stored in the Enhanced Binary Universal Form (EBUF) format. These data files have been reformatted and are provided (in ASCII format) by the Langley DAAC.

There are 10 variables in a NOAA wind profile record. Variables are separated by white space(s). The variable values are left-justified. These variables with their units are listed in order below.
| Variable Name | Unit |
|---|---|
| Height above station | Meters |
| Signal Power (0th moment) North | Decibels |
| Signal Power (0th moment) East | Decibels |
| Signal Power (0th moment) Vertical | Decibels |
| Mean Velocity (1st moment) North | Meters/Second |
| Mean Velocity (1st moment) East | Meters/Second |
| Mean Velocity (1st moment) Vertical | Meters/Second |
| Velocity variance (2nd moment) North | (Meters/Second)**2 |
| Velocity variance (2nd moment) East | (Meters/Second)**2 |
| Velocity variance (2nd moment) Vertical | (Meters/Second)**2 |

A general description of data granularity as it applies to the IMS appears in the EOSDIS Glossary.
The NOAA wind profiles data set consists of 25 ASCII files. A NOAA wind profiles file has multiple windprofiles records. Each file is named ci2_noawnd_yymmdd_6m, where yy is the year, mm the month, and dd the day when the data were collected. A wind profiles record starts with three header lines, followed by three lines of column headings, followed by windprofile data, and ends with the parameter "Profiler in checkout mode flag" line. The first header line contains date and time values, the second header line contains station latitude and longitude values, and the third header line contains the values for the parameters "height of station above sea level" and "height increment".
The data are in ASCII format.
