The Vegetation Condition data
selectable below are updated weekly and arranged by two week composite periods covering
the 1995 - 1999, 2001-2003, and 2004-2008 (as available) crop
seasons. A water vapor correction was applied by USGS to
data collected by NOAA-14 from the 1995 through the 1999 crop season.
Data from subsequent satellites (NOAA-16, NOAA-17) are not water vapor
corrected. Ratio derived products of a specific period to a previous comparable
date period are only created within images of the same satellite.
The NOAA-16 satellite collected images from the 2001 through 2003 seasons.
NOAA-16 started malfunctioning in early 2004, when a scan motor problem
caused a 'barcode' appearance.
Images from the NOAA-17
satellite replaced NOAA-16 starting in 2004. The
USGS released updated calibration coefficients for the NOAA-17 satellite
developed by NOAA after the 2004 growing season. Images available below
from the 2004 - 2008 growing seasons reflect the updated calibration
coefficients.
Animations of these images for a given year reveal how the vegetation
condition changed during that growing season.
