Suspect Product is degraded due to use of only two days of input data in the composite. Instrument data was available for days 2000 055 and 2000 056 only. Snow mapping errors may occur on the perimeters of snow fields, cloud edges and water boundaries. Validated Stage 2

(03/01/00)
2000 091
(03/31/00)
Inferred Passed Snow cover is mapped with reasonable accuracy. Snow errors are manifest in cells with very low snow percentages in regions where snow is unlikely based on climate or season. Discretion should be exercised in use of this product. Snow mapping errors may occur on the perimeters of snow fields, cloud edges and water boundaries. Products made for data day 2000073 using the data acquired between 2000076:18:45:00 and 2000076:19:10:00 and between 2000076:20:20:00 and 2000076:20:50:00 may have geolocation error casued by the spacecraft maneuver. Validated Stage 2

2001 120
(04/30/01)
Inferred Passed Snow cover is mapped with reasonable accuracy. Snow errors are manifest in cells with very low snow percentages in regions where snow is unlikely based on climate or season. Discretion should be exercised in use of this product. Snow mapping errors may occur on the perimeters of snow fields, cloud edges and water boundaries. Validated Stage 2

(05/31/01)
Suspect Some of the files may have large geolocation error. Use of incorrect ephemeris/attitude in processing of some of the MODIS L0 granules has resulted in geolocation error larger than 20m and this error has propogated into the downstream products. Discretion should be exercised in use of this product. Affected granules are from the three two hour periods starting 2001-05-29T14:00 (doy 149), 2001-05-30T16:00 (doy 150) and 2001-05-30T22:00 (doy 150). Validated stage 2

Failed L1B data was not available for data days 2001166 - 2001183. MODIS was OFF on these days after being shut off on 2001166 due to SAA.   Validated Stage 2
2001 182
(07/01/01)
2001 212
(07/31/01)
Suspect Product quality may have been effected due to use of only one day of input data since no L1B was available for data day 2001166 - 2001183. MODIS was OFF on these days after being shut off on 2001166 due to SAA. Discretion should be exercised in use of this product.   Validated Stage 2
2001 213
(08/01/01)
2002 059
(02/28/02)
Inferred Passed Snow cover is mapped with reasonable accuracy. Snow errors manifest in cells with very low snow percentages in regions where snow is unlikely based on climate or season. Discretion should be exercised in use of this product. Snow mapping errors may occur on the perimeters of snow fields, cloud edges and water boundaries. Products made for data day 2001273 using the data acquired between 2001275:18:50:00 and 2001275:18:55:00 may have geolocation error casued by the spacecraft maneuver. Validated Stage 2
2002 060
(03/01/02)
2002 090
(03/31/02)
Suspect Product quality may have been effected due to use of less than 8-days of data in the composite. MODIS was OFF during 2002073 - 2002087. Descretion should be exercised in use of this product.   Validated Stage 2
2002 091
(04/01/02)
2002 120
(04/30/02)
Suspect Product quality may have been effected due to use of less than 8-days of data in the composite. L1B data was not available for part of day 2002104 and all day 2002105. Descretion should be exercised in use of this product.   Validated Stage 2
