Global satellite remote sensing records show evidence of recent vegetation greening and an advancing growing season at high latitudes. Satellite remote sensing–derived measures of photosynthetic leaf area index (LAI) and vegetation gross and net primary productivity (GPP and NPP) from the NOAA Advanced Very High Resolution Radiometer (AVHRR) Pathfinder * Corresponding author address: J.

The Institute for Soil, Climate and Water developed an early warning and decision support system funded by the National Department of Agriculture. The system went operational in October 2000. The system is refered to as Umlindi ( Zulu word for the watchman) and provides information on fire, vegetation condition, water satisfaction index (crop yield prediction and drought monitoring model) and r...

An empirical approach for detecting polar lows is developed based on satellite data from two sensors: Synthetic aperture radar (SAR) wave mode image on board ERS-2 satellite and AVHRR image on board the National Oceanic and Atmospheric Administration (NOAA) family of polar orbiting platforms (i. e. POES). This approach is primarily based on 10m wind field and wave height besides the latitudinal...

Based on NOAA/AVHRR NDVI biweekly time-series data, the start and end of the growing season of Central Asia from 1982 to 2006 were estimated. Trend analysis results indicate an earlier green-up and a later dormancy over the entire area during the study period. For seven main vegetation types, the largest advance of greenup onset (0.597 days/year) occurs in cropland and the longest delay of dorm...

The spatial-temporal dynamics of forest fires for last five years in latitudinal range 40-74 degrees of the northern latitude are analyzed with using the data of the radiometer AVHRR/NOAA. It was shown that forest fires are observed from May till September, basically during three summer months with a maximum of the activity during the second half of summer. On a phase of a maximum of an 11-year...

Methods for absolute calibration of visible and near-infrared sensors using ocean and cloud views have been developed and applied to channels 1 (red) and 2 (near-infrared) of the Advanced Very High Resolution Radiometer (AVHRR) for the NOAA-7. -9 and -I I satellites. The approach includes two steps. First step is intercalibration between channels 1 and 2 using high altitude (12 km and above) br...

During the summer of 2002 the Center of Excellence in Remote Sensing Education and Research (CERSER) was established on the campus of Elizabeth City State University. It is the intent of CERSER to develop innovative and relevant research collaboration focused on coastal, ocean, and marine research. The project represents a joint effort by the Office of Naval Research (ONR), the MU-SPIN Office o...

[1] Satellite aerosol remote sensing entered a new era with the deployment of advanced satellite imaging instruments such as the Moderate Resolution Imaging Spectroradiometer (MODIS) on the NASA Terra and Aqua satellites. These new instruments provide the opportunity to learn more about aerosol properties than was possible using the simpler NOAA Advanced Very High Resolution Radiometer (AVHRR),...
