Question Description

Generating a Satellite map for you project proposal through MyNASAData.com

 

 

Assignment: Prepare an actual dataset map using real NASA data.

 

My NASA Data’s data visualization tool, Earth System Data Explorer (ESDE), is continuously updated with new data and is now organized by the spheres in the Earth System – the Geosphere, Hydrosphere, Cryosphere, Biosphere, and Atmosphere.

 

 

• Go to: https://mynasadata.larc.nasa.gov/

 

• Watch optional video “Getting started with Earth System Data Explorer.” This is optional, but it will give you a better idea on how it the tool works.

• After video, go back to homepage and click Visualize Data, then click Earth System Data Explorer. You will see a map layout.

 

• Choose a data set. (Click the “Data Set” bar on left of screen)

 

• Choose between Atmosphere, Biosphere, Cryosphere, Geosphere, hydrosphere.

 

• Select either All Data or Featured Phenomenon,

 

• Select a feature (may be several drop menus)

 

• After data set map loads, you will see the entire world with the dataset in map view. Zoom into the U.S. using the small World Map on left screen.  (Click the square box to zoom into the United States, then click Update plot. 

 

Some maps might be very pixelated, and that is okay.  It is real data!

 

• Replace Example image below with your new U.S. image. (Do this by clicking the Display link to download image located on the top left of main map). Write a caption for your figure using the Annotations you see above your map in the Earth System Data Explorer map.

 

(EXAMPLE Caption): Satellite Source: MODIS.  DESCRIPTION: This quantity describes the concentration of chlorophyll in oceans. Chlorophyll is a pigment that plants use to absorb sunlight, key to the process of photosynthesis. The higher the concentration, the greater amount of plant life in the oceans. These data have a grid spacing of 0.08 degrees longitude and 0.08 degrees latitude.)

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

2) Repeat the steps above, but this time use a different dataset.  Zoom in to an area that you are interested in around the world and cut and paste map here.  Once again, add the caption for your figure using the caption above the Earth Data Explorer map.

(EXAMPLE Caption: SOURCE: NCEP/NCAR.   DESCRIPTION: These data show the daily average relative humidity near the surface. The data have a grid spacing of 2.5 degrees longitude and 2.5 degrees latitude. Relative humidity is a measure of how much water vapor is in the air. It is defined as the ratio of the amount of water vapor in the air to the amount of water vapor that could be in the air if it was full of water vapor (saturated). A relative humidity value of 100% means that the air is saturated with water vapor and condensation is likely to occur.)
