Data Extraction Tools
The data extraction tools allow the user to extract and read the data from the data files. The data extraction tools that are availabe are the following; click on the links for more information about that tool:
Tool Name | extract.pro |
---|---|
Applicable Data Sets | DMSP SSM/I Daily Polar Gridded Brightness Temperatures Nimbus-5 ESMR Polar Gridded Brightness Temperatures Near Real-Time DMSP SSM/I Daily Polar Gridded Brightness Temperatures |
Description | IDL program that allows you to open a brightness temperature grid file and read it into an array, making it available for further manipulation in IDL or to write to hard disc. After the program has read the user-indicated time range, an array is returned with a 2-byte integer array of brightness temperatures expressed in tenths of a kelvin (0.1 K). For example, a value of 2358 translates to 235.8 K. |

Applicable Data Sets | Nimbus-5 ESMR Polar Gridded Sea Ice Concentrations Sea Ice Concentrations from Nimbus-7 SMMR and DMSP SSM/I Passive Microwave Data Bootstrap Sea Ice Concentrations from Nimbus-7 SMMR and DMSP SSM/I Near-Real-Time DMSP SSM/I-SSMIS Daily Polar Gridded Sea Ice Concentrations |
Description | IDL program that extracts a time series of polar sea ice data. The extraction routine works on both the daily and monthly sea ice files allowing users to select and display sea ice concentrations. For monthly data, users may select which image threshold to view (0, 5, 10, or 15% ice cut off). |
