Part 1: NASA NEO Data Analysis Techniques1
So far you have primarily used NEO as a portal for downloading images. In this part, you will explore the relationship between Aerosol Optical Thickness (AOT) and Carbon Monoxide (CO) using the Image Composite Explorer (ICE), NEO's buit-in java program for image analysis. ICE analyzes remotely-sensed observations of various Earth variables, provides the exact value of those variables at a given place in an image, and plots the results of analyses using a variety of graphing techniques.
Load Two Datasets into NEO/ICE for Analysis
- Go to the NASA Earth Observations (NEO) website and select the September 1, 2005 to October 1, 2005 images of Aerosol Optical Thickness (AOT) and Carbon Monoxide (CO), loading them for analysis in ICE.
- Go to the NASA Earth Observations (NEO) website. The site opens displaying the Blue Marble Data set. You will set the search parameters to locate two monthly images for comparison.
- Set the Duration to month and the Date Range to from September 1, 2005 to October 1, 2005. Then Click Search NEO.
- The search returns a list of datasets matching the search criteria. The first dataset in the Matching Datasets list is displayed in the map area.
- Scroll down the list and click the radio button for the Aerosol Optical Thickness (Aqua/MODIS) dataset. Then click the select button.
- The Aerosol Optical Thickness image is displayed for the month requested. Click Analyze this image.
