Using vegetation indices for soil-moisture retrievals from passive microwave radiometry [PDF]

open access: yesHydrology and Earth System Sciences, 2001
Surface soil moisture and the nature of the overlying vegetation both influence microwave emission from land surfaces significantly. One widely discussed but underused method for allowing for the effect of vegetation on soil-moisture retrievals from ...

Brain temperature measurement by microwave radiometry in new born infants [PDF]

open access: yes, 2001
Hypoihermal neural rescue therapy has been recently considered for new-horn infants who have suffered hypoxia-ischaemia. The treatment it based on a moderate cooling of brain, which can he safely performed if the deep head temperature is atraumatically ...

Adaptive filter for microwave radiometry

open access: yesElectronics Letters, 1970
An adaptive filter, which combines the advantages of both short (about 0.5 s) and long (about 2 min) integrating time constants, is described. The recording time constant will be long for a steady level of input signal, but will proportionally shorten when there is a change in the average level of the input signal. If steady conditions continue after a

Time-dependent microwave radiometry for the measurement of temperature in medical applications [PDF]

open access: yes, 2004
Microwave radiometry has been considered for the noninvasive monitoring of internal temperature in biological bodies when the temperature is varied under the control of external sources and contacting fluid.

Envisat - taking the measure of North Atlantic storms [PDF]

open access: yes, 2007
Envisat carries a number of sensors able to provide quantitative information on raining clouds: AATSR delivers information on cloud microphysics (particle size, temperature etc.), MWR-2 gives columnar totals for liquid and vapour forms of water, and RA-2

Topographic Effects on the Surface Emissivity of a Mountainous Area Observed by a Spaceborne Microwave Radiometer

open access: yesSensors, 2008
A simulation study to understand the influence of topography on the surfaceemissivity observed by a satellite microwave radiometer is carried out. We analyze theeffects due to changes in observation angle, including the rotation of the polarization plane.
