2) What is the name of the original archived data set from which this
     GEWEX-RFA subset was produced?
	DLR-ISIS

3) Is the original archived data set currently available from another
     data center or web site?
     If so, please list addresses or URLs:
	http://www.pa.op.dlr.de/ISIS/

4) Brief data description:  A reference or URL for the complete original
     archived data set documentation, followed by a brief summary of
     features of particular relevance to the RFA submission (such as gap
     filling method), is the preferred approach.
     (Items of interest: input data streams, name of algorithm used to
     produce data, start and end time of data, gaps in spatial or temporal
     coverage, and data quality issues, etc.).

5) History of updates and changes.  If you resubmit a new version of
     any part of this data product to GEWEX-RFA, please use this space to
     record the reasons for the new submission (i.e., fixed error in ___
     parameter; changed to area-weighted spatial averaging, etc.)  Please
     specify the parameter(s) affected, new RFA number(s), and the date of
     the change.
