Some tips on searching for data using Earthdata Search.
While Earthdata Search's free text search field will attempt to understand free text queries. e.g. "land surface temperature over Uganda for the last 10 years" -- it sometimes doesn't return useful results. If the free-text search includes the name of a location that Earthdata Search does not recognize, you may not get any results at all.
For best results,
So for example, to search for "land surface temperature over Uganda for the last 10 years"
You can download a granule, multiple granules, a single collection, or multiple collections.
To download a granule, multiple granules, or a collection
Click a collection to view its granules.
In granule view, you'll see only the granules for the collection that fit your spacial and temporal constraints.
You can further narrow the granules selected using the "Granule Search" text field, the "Filter granules" button (the funnel icon) on the right, and the date slider at the bottom of the screen.
To download all selected granules, click the "Download Data" button on the right hand side of the screen.
To download an individual granule, do one of the following:
After clicking "Download Data" or "Configure and download single granule data," you will see one or more of the following ordering options, depending on what the data provider supports:
To download multiple collections
In granule view, you can filter the granules selected using any combination of the following:
To search for a specific granule file, you will need to know the name or id of the collection name to which it belongs.
When you have that, search for the collection, and then filter the collection's granules using the filename.
For example, to search for file N42W072.zip in in collection ASTGTM:
"Customizations" refers to data customization options offered by data providers for select products. These may include data reformatting (e.g. to NetCDF, GeoTIFF, KLM and other file formats), data reprojection, data subsetting, and other options. Collections for which customizations are available are indicated with the label "CUSTOMIZABLE" following the collection name.
To see only customizable products, check the "Features | Customizable" checkbox on the left in collection view.
To specify a customization option, when placing an order choose the "Customize Order" option.
Please note that customization services are not offered for all products, and not all customizable products support every option.

More info:
"MODIS Land products use the Sinusoidal grid tiling system. Tiles are 10 degrees by 10 degrees at the equator. The tile coordinate system starts at (0,0) (horizontal tile number, vertical tile number) in the upper left corner and proceeds right (horizontal) and downward (vertical). The tile in the bottom right corner is (35,17)."
