Errata for Polar Pathfinder Sampler CD-ROM documentation for 1.25 km AVHRR product.




In the documentation on the Polar Pathfinder Sampler CD-ROM for the 1.25 km AVHRR products, an error has been found. Under Section D. (Data Processing and Product Description), subsection 1. (Channel One through Five Radiances), there is a discussion of the process to maximize higher-resolution coverage. Instead of relaxing the scan angle and local-time-proximity requirements to 35 degrees and 1.5 hours, respectively, as stated in the documentation on the Sampler CD-ROM, the scan angle and local-time-proximity requirements were relaxed to 46 degrees (not 35) and 3 hours (not 1.5), respectively. Similarly, in that same paragraph, instead of including data with scan angles as great as 35 degrees and with local time differences (from the composite's target local time) of as much as 1.5 hours, as stated in the documentation on the Sampler CD-ROM, where swaths are missing, partial compensation for missing data is made by including data with scan angles as great as 46 degrees (not 35) and with local time differences (from the composite's target local time) of as much as 3 hours (not 1.5).
