Avhrr data for land use

AVHRR Data for Land Use

Sensor: Advanced Very High Resolution Radiometer (AVHRR)

Satellites:NOAA-7, 9, 11, 14, 16, 17 (morn.),18, 19

Data Resolution:Spatial - 4 km (GAC), 8 & 16 km; Temporal - 7-day composite

Period:30-year(1981-2010)

Coverage:World(75 N to 55 S)

Channels:VIS (ch1), NIR (ch2), Thermal (ch4, ch5)


Theory vegetation vs vis nir reflectance

Vegetation condition index (VCI), values 0 - 100

VCI=(NDVI-NDVImin)/(NDVImax-NDVImin)

NDVImax, and NDVImin – climatology (1981-2000 maximum and minimum NDVI for a pixel;

Temperature condition index (TCI), values 0 - 100

TCI=(BTmax-BTmin)/(BTmax-BTmin)

NDVImax, and NDVImin – climatology (1981-2000 maximum and minimum NDVI for a pixel

Vegetation Health Index (VHI), values 0 – 100

VHI=a*VCI+(1-a)*TCI

0 – indicates extreme stress

100 – indicates favorable conditions

  • Vegetation Health (red) deteriorated from April through the end of the growing season, especially in the main areas of winter wheat

  • VHI is derived from NOAA/AVHRR data and estimates greenness, vigor and thermal conditions of vegetation

Russia produces 65% WW & 35% SW

  • Figure shows dynamics of Vegetation health (VH)

  • 2007 WW analogue was 2001 VH

  • WW yield is expected at or 1-3% below LTT or 1.9 t/ha

  • Figure shows dynamics of Vegetation health (VH)

  • 2007 SW analogue was 2001 VH

  • SW yield is expected 5-7% above long-term trend (LTT)

Total wheat is expected at or slightly below LTT (1.96 t/ha)
