Scientific Data Sets Name Data Type Dimensions ---- --------- ---------- Burn Date int16 YDim:MOD_Grid_Monthly_500m_DB_BA, XDim:MOD_Grid_Monthly_500m_DB_BA Description: Ordinal date of burn, with 0 = unburned. A value of -1 is used to flag missing data, and a value of -2 is used to flag grid cells located in water. SDS Attributes: Attribute Type Quantity Value --------- ---- -------- -------- valid_range int16 2 0, 366 long_name string 19 "ordinal day of burn" _FillValue int16 1 -1 water int16 1 -2 ============================================================================= Name Data Type Dimensions ---- --------- ---------- Burn Date Uncertainty int8 YDim:MOD_Grid_Monthly_500m_DB_BA, XDim:MOD_Grid_Monthly_500m_DB_BA Description: Temporal uncertainty in burn date. SDS Attributes: Attribute Type Quantity Value --------- ---- -------- -------- units string 4 "days" ============================================================================= Name Data Type Dimensions ---- --------- ---------- QA int8 YDim:MOD_Grid_Monthly_500m_DB_BA, XDim:MOD_Grid_Monthly_500m_DB_BA Description: Product quality assurance flags. Bit Description --- ----------- 0 land/water flag 0 = water 1 = land 1 valid data flag 0 = missing data 1 = valid 2 shortened mapping period (0 = false, 1 = true) 3 class updated during contextual relabeling phase (0 = false, 1 = true) 4 unused (set to 0) 5-7 unburned grid cell special-condition code 0 = none or not applicable (e.g., grid cell is burned) 1 = valid observations spaced too sparsely in time 2 = too few training observations 3 = apparent burn date at limits of time series 4 = apparent persistent water contamination 5 = persistent hotspot Bits 5-7 provide an explanation for any grid cells that were summarily classified as "unburned" by the mapping algorithm due to special circumstances. The vast majority of unburned grid cells do not fall into this category and will have a special-condition code of 0 (as will all burned, missing-data, and water grid cells).
