Multifrequency Microwave Emission from Forests
نویسندگان
چکیده
Retrieving information on forest biomass and soil under vegetation is crucial for all studies concerning global changes and carbon balance. The capability of microwaves in penetrating vegetation covers is well known, but only few studies have investigated emission from soil under forests and the contribution of single tree elements to total radiation. To further examine quantitatively these aspects a study has been carried out by using ground based multifrequency radiometric observations and model analysis. The results of this study made it possible to evaluate the contribution of the tree components to total emission and their effects on soil moisture measurement.

The sensitivity of microwave emission to biomass and biophysical properties of crops and forests has been proved in several experimental and theoretical studies. Experimental investigations on microwave emission from crops carried out since early 1980s by using ground based and airborne sensors demonstrated that useful information on vegetation covered soils can be obtained by combining brightn...
متن کاملThe effects of forest canopies and of the underlying soil moisture on microwave emission
Forests are important interfaces between soil and atmosphere as they play a significant role in the water and gas exchanges (mainly O2 and CO2). Due to their capabilities in reducing evaporation from the surfaces and to intercept rainfalls, they are able to substantially modify the moisture behaviour of underneath soils. On the other hand, the moisture conditions of soils influence the evapotra...
متن کاملFiltering techniques for the detection of Sunyaev - Zel ’ dovich clusters in multifrequency CMB maps
The problem of detecting Sunyaev-Zel’dovich (SZ) clusters in multifrequency CMB observations is investigated using a number of filtering techniques. A multifilter approach is introduced, which optimizes the detection of SZ clusters on microwave maps. An alternative method is also investigated, in which maps at different frequencies are combined in an optimal manner so that existing filtering te...
متن کاملFree-free Emission at Low Radio Frequencies
We discuss free-free radio emission from ionized gas in the intergalactic medium. Because the emissivity is proportional to the square of the electron density, the mean background is strongly sensitive to the spatial clumping of free electrons. Using several existing models for the clumping of ionized gas, we find that the expected free-free distortion to the cosmic microwave background (CMB) b...
متن کاملA multifrequency angular power spectrum analysis of the Leiden polarization surveys
The Galactic synchrotron emission is expected to be the most relevant source of astrophysical contamination in cosmic microwave background polarization measurements, at least at frequencies ν < ∼ 100 GHz and at angular scales θ > ∼ 30′ . We present a multifrequency analysis of the Leiden surveys, linear polarization surveys covering essentially the Northern Celestial Hemisphere at five frequenc...
