Passive microwave remote sensing of the atmosphere and ocean
Proceedings of the Indian Academy of Sciences Section C: Engineering Sciences, 1983The microwave remote sensing experiments conducted during the last decade using airborne and spaceborne sensors are now evolving as operational spacecraft observation systems. Microwave sounding unit (MUS) onboard TIROS-N regularly provides global atmospheric temperature profile required for numerical weather prediction.

Passive microwave remote sensing of soil moisture
International Journal of Remote Sensing, 1985Abstract Results of radiometric measurements over bare soil obtained with a horizontally polarized microwave radiometer at 19·1 GHz frequency are presented. Radiometer measurements were made with incidence angles varying from 10 to 50°. Ground-truth acquisition of soil moisture in the 0–1 cm layer and of soil temperature near the surface was made ...

Passive microwave remote sensing of vegetation biomass
Proceedings of IGARSS '94 - 1994 IEEE International Geoscience and Remote Sensing Symposium, 2002Experimental and theoretical investigations carried out over the past years at CNR in Florence and by other scientists worldwide, have pointed out that microwave emission is sensitive to vegetation biomass. The potential of microwave radiometry in the detection of vegetation biomass on different spatial scales has been further investigated by analyzing

Passive Microwave Remote Sensing Contribution to Hydrological Variables
Surveys in Geophysics, 1991Physical principles governing passive microwave remote sensing of hydrological variables are outlined and illustrated by actual observations by ground-based, air-borne and space-borne microwave radiometers operating at different frequencies. Specific hydrological variables addressed in this paper are soil moisture, seasonal inundation of rivers and ...

Passive microwave remote sensing for security applications
2007 European Radar Conference, 2007The security of persons or sensitive infrastructures is of increasing importance. Passive microwave remote sensing allows a daytime-independent non-destructive observation and examination of the objects of interest without artificial exposure under nearly all weather conditions.

Role of Passive Microwave Remote Sensing in Improving Flood Forecasts
IEEE Geoscience and Remote Sensing Letters, 2009Accurate information concerning antecedent soil moisture conditions is a key source of hydrologic forecasting skill for regional-scale flooding events occurring over time scales of days to weeks. Remotely sensed surface soil moisture observations are a viable source of such information and can potentially improve flood peak timing and magnitude ...

Passive microwave remote sensing of snow constrained by hydrological simulations
IEEE Transactions on Geoscience and Remote Sensing, 2001This paper describes a snow parameter retrieval algorithm from passive microwave remote sensing measurements. The three components of the retrieval algorithm include a dense media radiative transfer (DMRT) model, which is based on the quasicrystalline approximation (QCA) with the sticky particle assumption, a physically-based snow hydrology model (SHM)

Combined active and passive microwave remote sensing of snow in Finland
IGARSS 2003. 2003 IEEE International Geoscience and Remote Sensing Symposium. Proceedings (IEEE Cat. No.03CH37477), 2004We examined the use of data from active (QuikScat on SeaWinds) and passive (SSM/I on DMSP) space-borne microwave sensors for monitoring key snow parameters in Finland. The feasibility of these data for the task was determined both separately and using a combined data set.

Intercomparison of Electromagnetic Models for Passive Microwave Remote Sensing of Snow
IEEE Transactions on Geoscience and Remote Sensing, 2006Electromagnetic models can be used for understanding the interaction between electromagnetic waves and matter, interpreting experimental data, and retrieving geophysical parameters. Comparing the results of different snow models, when driven with the same set of input parameters, can benefit remote sensing of snow.
