carswell, A new era in hurricane reconnaissance: real time measurement of surface wind structure and intensity via microwave remote sensing.

The new NOAA/AOC Stepped Frequency Microwave Radiometer represents a potentially significant advancement in the remote measurement of hurricane near-surface wind speeds, most notably at speeds >50 m s −1. This improvement is due to both refined remote sensing technologies, and more accurate ground-truth data in the form of GPS dropwindsonde.

aircraft can fly through the storm and provide precipitation estimates from passive and active The first experimental SFMR rain rate measurements were made in Hurricane Allen in by the first SFMR instrument built by the National temperature measurements by using a microwave radiative transfer model.

The second SFMR. Hurricane Allen () by using airborne radar rainfall estimation. In this study, the SFMR rain rate measurements in tropical cyclones are evaluated against airborne radar data. The radar data used here are from the Lower Fuselage (LF) radar and the tail (TA) radar on the NOAA WP-3D aircraft.

Remote Sens., vol. 50, issue: 1, pp. Jan Title: Professor at University of Central. TROPICS will provide rapid‐refresh microwave measurements (median refresh rate better than 60 min for the baseline mission) which can be used to observe the thermodynamics of the troposphere and precipitation structure for storm systems at the mesoscale and synoptic scale over the entire storm life cycle.

An example of NASA high-altitude thermodynamic profiling integrated with active microwave sensing and in situ measurements to understand hurricane evolution is given in Braun et al.

Abstract. The interest in passive microwave remote sensing of the ocean developed in the mid ’s when the analytical work of Stogryn indicated that radiometric emission from the ocean depends upon the degree of surface roughness.

Atmospheric Sciences Research Center University at Albany CESTM Building Fuller Road Albany, New York () Fax: () Microwave sensing encompasses both active and passive forms of remote sensing.

As described in Chapter 2, the microwave portion of the spectrum covers the range from approximately 1cm to 1m in wavelength. Because of their long wavelengths, compared to the visible and infrared, microwaves have special properties that are important for remote.

This book provides state-of-the-art coverage for making measurements on RF and Microwave Components, both active and passive. A perfect reference for R&D and Test Engineers, with topics ranging from the best practices for basic measurements, to an in-depth analysis of errors, correction methods, and uncertainty analysis, this book provides.

Passive System. For their first project, McIntosh and Swift spent 18 months building a passive system that merely reads signals reflected from earth, as opposed to an active radar system which sends down its own beam of microwave radiation and reads the return. Departmental colleague David M.

Pozar designed the aluminum antenna, built on campus. The crystalline structure of ice typically emits more microwave energy than the liquid water in the ocean. Thus, sensors that detect passive microwave radiation can easily distinguish sea ice from ocean.

A major drawback to measuring passive microwave radiation is. The first SFMR measurement for hurricane Allen was made using the National Oceanic Atmospheric Administration (NOAA) Hurricane Research Division’s (HRD’s) WC aircraft in [1].

Sincesea surface winds in hurricanes have been Some space-borne active and passive microwave sensors have been used to monitor TC. the book D. Pozar, Microwave Engineering (third edition). Hoboken, NJ: Wiley, Much other information is covered in this text as well, so it is one of the books that all RF and microwave engineers should own.
