Infrared and microwave measurements across the ITC [PDF]
Analysis is presented of data obtained from Nimbus 3 infrared measurements of the Intertropical Convergence Zone (ITC) over the tropical oceans. The ITC is characterized by a cloud belt with a varied structure of single to double lines or clusters along ...

The Planck-LFI instrument: analysis of the 1/f noise and implications for the scanning strategy [PDF]
, 1999 We study the impact of the 1/f noise on the PLANCK Low Frequency Instrument (LFI) osbervations (Mandolesi et al 1998) and describe a simple method for removing striping effects from the maps for a number of different scanning stategies.

Intercomparison of integrated water vapour measurements
Meteorologische Zeitschrift, 2006 Measurements of tropospheric integrated water vapour (IWV) made with two microwave radiometers (ASMUWARA, TP/WVP-3000), GPS, and radiosondes (SRS 400) during the Temperature, hUmidity, and Cloud (TUC) profiling campaign under mid-latitude conditions in ...

Microwave remote sensing of water vapor in the atmosphere [PDF]
Geographica HelveticaWater vapor in the atmosphere plays a crucial role in climate and in atmospheric processes. Due to its long chemical lifetime it can be used as a tracer for investigations of dynamical processes in the middle atmosphere.

The estimation of the propagation delay through the troposphere from microwave radiometer data [PDF]
The uncertainity in propagation delay estimates is due primarily to tropospheric water, the total amount and vertical distribution of which is variable. Because water vapor both delays and attenuates microwave signals, the propagation delay, or wet path ...

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

The Temperature of the CMB at 10 GHz
, 2004 We report the results of an effort to measure the low frequency portion of the spectrum of the Cosmic Microwave Background Radiation (CMB), using a balloon-borne instrument called ARCADE (Absolute Radiometer for Cosmology, Astrophysics, and Diffuse ...

Microwave Radiometer Resolution Optimization Using Variable Observation Times
Remote Sensing, 2010 This manuscript first revises the performance of total power, Dicke-type and noise-injection microwave radiometers. Equations for the radiometric resolution are revised or derived, and their performance in terms of the radiometric resolution improvement ...

Microwave Remote Sensing of Soil Moisture [PDF]
, 1985 Because of the large contrast between the dielectric constant of liquid water and that of dry soil at microwave wavelength, there is a strong dependence of the thermal emission and radar backscatter from the soil on its moisture content.
