[Abstract]

　Two categories of satellite sensors were used for observing conditions of soils and vegetation in the west Siberian lowland; one is a high-spatial-resolution sensor(SPOT/HRV) and the other is a wide-coverage coarse-spatial-resolution sensor(NOAA/AVHRR). A SPOT/HRV image was used for detailed classification of wetland ecosystems at Plotnikovo test site. Methane emission from the image area was estimated by combining the result of ecosystem classification with ground methane flux data. This methane emission estimate was about 34% less than that obtained from airborne methane measurements. NOAA/AVHRR data were used for monitoring seasonal changes of vegetation and surface temperatures in west Siberian wetlands. From the time histories of NDVI values derived from AVHRR data, land cover types were classified in the whole west Siberian lowland area. Seasonal changes of ground surface temperature in west Siberia were estimated using AVHRR thermal infrared channels.
