| 2006-05-02 | An error was found by NASA in the original data for weeks 12 and 17 of 1987 in the NESDIS snow cover data. The corrected files are now on the BADC but the ASCII data fields are two characters wide rather than the original four. For this reason the originals are still available in place and are called y87w12.nsc_errors and y87w17.nsc_errors. |
