SUMMARY Here we report a method for estimating ecosystem respiration (R e) by exclusive use of remotely sensed land surface temperature (T r) from NASA's moderate resolution imaging spectroradiometer (MODIS) sensors. A combination of daytime and nighttime MODIS T r data was used to model an 8-day mean value of land surface temperature (T r(mean)), which was then used in a modified Arrhenius-bas...

This study used MODIS active fire detections and associated fire radiative power estimates to characterise bush fires in the savanna region of Australia’s Northern Territory. In contrast to other sensors MODIS has dedicated fire channels that rarely saturate over fires, enabling fire detections during the day and estimates of fire radiative power. Using number of dayand night-time fire detectio...

Terra and Aqua, 2 satellites launched by the NASA-centered international Earth Observing System project, house MODIS (Moderate Resolution Imaging Spectroradiometer) sensors. Moderate resolution remote sensing allows the quantifying of land surface type and extent, which can be used to monitor changes in land cover and land use for extended periods of time. In this paper, we propose applying a p...

Aerosol detection and monitoring from satellite platforms has made significant advances over the past decade. While several state-ofthe-art aerosol retrieval techniques provide aerosol properties at global scale, the more detailed spatial patterns remain unknown because most of the relevant satellite sensors operate at coarse resolution. A new aerosol retrieval algorithm for the Moderate Resolu...

The Landsat ETM+ has shown great potential in agricultural mapping and monitoring due to its advantages over traditional receive procedures in terms of cost effectiveness and timeliness in availability of information over larger areas and ingredient the temporal dependence of multitemporal image data to identify the changing pattern of vegetation cover and consequently enhance the interpretatio...

[1] There exist numerous global aerosol products derived from various satellite sensors, but little insight has been gained about their compatibility and quality. This study presents a comparison of two prominent global aerosol products derived over oceans from the advanced very high resolution radiometer (AVHRR) under the Global Aerosol Climatology Project (GACP) (Mishchenko et al., 1999) and ...

While satellite-based monitoring of vegetation activity at the earth’s surface is of vital importance for many eco-climatological applications, the degree of agreement among certain sensors and products providing estimates of the Normalized Difference Vegetation Index (NDVI) has been found to vary considerably. In order to assess the extent of such differences in highly heterogeneous terrain, w...

For near real-time water applications, the Moderate Resolution Imaging Spectroradiometers (MODIS) on Terra and Aqua are currently the only satellite instruments that can provide well-calibrated top-of-atmosphere (TOA) radiance data over the global aquatic environments. However, TOA radiance data in the MODIS ocean bands over turbid atmosphere in east China often saturate, leaving only four land...
