2000 056
(02/25/00)
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
2000 057
(02/26/00)
2000 112
(04/21/00)
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

(04/29/00)
Suspect MODIS nadir aperture door was closed part time on 2000116 and 2000119, all time on 2000117 and 2000118.   Validated Stage 2

(08/03/00)
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. Validated Stage 2

(08/04/00)
2000 232
(08/19/00)
Suspect MODIS-L1B data was not available for days 2000219 - 2000230 due to L1B formatter anamoly.   Validated Stage 2

2001 144
(05/24/01)
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
2001 145
(05/25/01)
2001 152
(06/01/01)
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
2001 153
(06/02/01)
2001 160
(06/09/01)
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. A climatologically based snow mask is applied to alleviate some errors of snow mapping. Validated Stage 2
2001 161
(06/10/01)
2001 168
(06/17/01)
Suspect Product quality may have been effected due to use of only 5 days 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 169
(06/18/01)
2001 176
(06/25/01)
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 177
(06/26/01)
2001 184
(07/03/01)
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

(07/04/01)
2002 072
(03/13/02)
