The standard AIRSAR data files are included on the CD-ROM/DVD along with browse GIF image files.  Please note that due to large file sizes, CD-ROM’s may be too small to hold all the data, and the data might be spread across multiple discs.  For more information about what these files are and the format, please visit the http://airsar.jpl.nasa.gov web page.

We applied a P-band filter to reduce the impact of interference in the P-band imagery. However, there may be a small amount of p-band interference still present in the data. In addition, in some cases, the P-band filter is not effective. Because the P-band filter may adversely impact the calibration of the data, we provide both the filtered and unfiltered files.

The co-registration of the P-band data to the L-band data set can be in error by several pixels. We recommend that you inspect this carefully, taking into consideration 1) the oversampling of the P-band data, 2) the different scattering mechanisms that may occur at the different bands, and 3) the varying penetration into targets that may occur. The co-registration of the P-band data to the C and L-band data set can be in error by several pixels. We recommend that you inspect this carefully, taking into consideration 1) the oversampling of the P-band data, 2) the different scattering mechanisms that may occur at the different bands, and 3) the varying penetration into targets that may occur. The mode for this data (80 Mhz L-band, 20 Mhz P-band) does not include C-band data acquisition.
Additional Comments
For the L-HV and L-VV bands, the caltone phase shows off-nominal drift of 50 degrees. The caltone gain is stable.
