Missing Pixels

Missing pixel information allows users computing various statistics from the data such as ice extent, to quickly determine the viability of including a particular day's data in their calculations. For each daily image, NSIDC sums the total number of missing pixels for the entire image to determine the percentage of missing pixels. GIF-formatted graphs of missing pixels are also provided.

File names are missing_pixels_F13.n (and .s). The .n represents Northern Hemisphere, and the .s represents Southern Hemisphere. Data are in ASCII text format, with columns for date, number of missing pixels, and the percentage of missing pixels.

Data are available via FTP
