There are two sections on a Search page. The column to the left is the Search Criteria section. The area to the right is the File List section.
Search Criteria
In order to search for data that will appear in the File List section, first set your search criteria as detailed below and then press the Search button.
Start & End Time
Here is where you choose a range of times to search for data from.
| · | The first row of drop down boxes contains the starting date and time.
|
| · | The second row of drop down boxes contains the ending date and time.
|
Orbit Selection
Here is where you can search for orbits by orbit number or by circular geographic area.
The first line contains text boxes for searching by orbit number.
| · | Single - single orbit number to search for. Entering a value here overrides anything in the "First" and "Last" text boxes.
|
| · | First - first orbit number in a range of orbits to search for. Leaving "Last" blank will search for any orbits greater than or equal to this "First" orbit number.
|
| · | Last - last orbit number in a range of orbits to search for. Leaving "First" blank will search for any orbits less than or equal to this "Last" orbit number.
|
The second line contains text boxes for searching by circular geographic area. An orbit will be selected if any part of it falls within the specified geographic area.
| · | Lat - latitude of the center point.
|
| · | Lon - longitude of the center point.
|
| · | Rad - radius of the circular area in kilometers.

Orbit Selection
In addition to the basic options mentioned above, here are a few new orbit selection criteria.
| · | Good - Minimum percentage of good data required from an orbit. Bad profiles are ones that are missing or dropped due to a bad CRC.
|
| · | Land - Minimum percentage of data over land required from an orbit.
|
| · | Only orbits that contain calibration manuevers - Check this box if you would only like orbits that contain calibration manuevers.

Product Selection
A drop down box is added to the right of the CloudSat product drop down box.
| · | The new drop down box contains the output format of the data. Formats include HDF-EOS4 and binary.

Output Subsetting
This new section allows you to subset your output data.
| · | Name - Choose a unique subset name for identifying the output files that will be listed. (If you choose specific fields for your subset, you MUST name the subset.)
|
| · | Lat/Lon/Rad subset - Check this box if you would like to subset the data based on the Lat, Lon, and Rad entered in the Orbit Selection section above.
|
You can also choose to select only specific fields from a product for your output files. These fields can be selected on a per product basis and will be available if you have selected a specific product from the drop down list in the Product Selection section above.
| · | Header Fields - Check boxes to select specific header fields. Click on "Select All" to select all header fields or click on "Unselect All" to unselect all header fields.
