S'COOL: Using the Database
As explained elsewhere, processing the satellite data can take some time. For example, a corresponding subset of the CERES data will often be processed within a week. Geostationary (or GEO) satellite data on the other hand is received daily. As they are processed, CERES and GEO satellite data corresponding to S'COOL observations are added to the S'COOL Observation database, and participants will get an automated email with a direct link to the comparison. You can also access the S'COOL and satellite correspondences in the following two ways.
1. Interactive Access to the S'COOL Observation Database
Choosing one of the links below will lead to a page where you can specify a search.
You can get up to 1000 S'COOL reports using this interactive search feature.
Note the new option to return only ground observations with matching satellite data! You may want to visit an FAQ with some common questions about comparing the ground observation report to the satellite retrieval.
2. Download an Excel File
If your goal is to analyze lots of matching data, this is the easier route.
To download these files, DO NOT CLICK on the link. On a Macintosh, hold down the option key and then
click. On a PC, hold down the Control key and then click. Once you have the file on your computer,
open Excel (or similar spreadsheet application) and open the file from within the program.
For additional details about what is in these files, please review the data description file. Note that some items, such as cloud type, have already been decoded in the above files.

that has some ideas for how to approach the data analysis.
We also have two Excel files which you can use as a starting point for analysis:
- Excel file with 4 simple ideas (2.3 MB)
- Excel file with 1 more involved idea (2.9 MB)
Reports on comparisons
A poster analyzing S'COOL correspondences was presented at the 2008 Fall Meeting of the American Geophysical Union in San Francisco in Dec. 2008. You can view the poster, and also hear Stephanie talk about her experience in a You Tube video.
Earlier, an analysis of these correspondences was prepared for the 13th Conference on Satellite Meteorology and
Oceanography of the American Meteorological Society and was presented in Norfolk, VA on Sept. 23rd, 2004.
You can see the abstract of
this paper or view the paper itself (pdf; 2.3 Mb).
You can also see the Power point slides presented at the meeting. The presentation
was recorded by AMS, and you can find that here (if you can get the WebEx system to work). My apologies for the quality of the audio. That's my soft-spoken voice. - Lin H. Chambers
An Excel file with 9172 S'COOL and CERES correspondences as of August, 2004, that was used in this analysis is also available The file includes some explanations
of the data. Examples are also available to give you ideas and tools for analysis.
Exploring Satellite Imagery
Your observation records include a direct link to the corresponding MODIS satellite image. You can also explore near real-time
and archival MODIS satellite imagery from around the world on the MODIS Rapid Response website. We have created a guide for S'COOL participants to help you use this site.
