Thermal microwave emissions from vegetated fields: A comparison between theory and experiment [PDF]

open access: yes
The radiometric measurements over bare field and fields covered with grass, soybean, corn, and alfalfa were made with 1.4 GHz and 5 GHz microwave radiometers during August - October 1978.

Mapping individual logical processes in information searching [PDF]

open access: yes
An interactive dialog with a computerized information collection was recorded and plotted in the form of a flow chart. The process permits one to identify the logical processes employed in considerable detail and is therefore suggested as a tool for ...

A multi-frequency radiometric measurement of soil moisture content over bare and vegetated fields [PDF]

open access: yes
A USDA Beltsville Agricultural Research Center site was used for an experiment in which soil moisture remote sensing over bare, grass, and alfalfa fields was conducted over a three-month period using 0.6 GHz, 1.4 GHz, and 10.6 GHz Dicke-type microwave ...

Radiometric measurements over bare and vegetated fields at 1.4 GHz and 5 GHz frequencies [PDF]

open access: yes
Microwave emission from bare and vegetated fields was measured with dual polarized radiometers at 1.4 GHz and 5 GHz frequencies. The measured brightness temperatures over bare fields are shown to compare favorably with those calculated from radiative ...
