On the accuracy of retrieved wind information from Doppler lidar observations [PDF]

open access: yes, 2003
A single pulsed Doppler lidar was successfully deployed to measure air flow and turbulence over the Malvern hills, Worcester, UK. The DERA Malvern lidar used was a CO2 µm pulsed Doppler lidar.

The Reflectance Distribution of Shallow Cumulus and Its Environs From High Spatial Resolution ASTER Images

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 3, 16 February 2026.
Abstract We investigate the 1D reflectance distribution of shallow cumulus as a function of cloud size, using high‐spatial‐resolution observations from the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER). Reflectance transects through clouds are compared between Inner Mongolia and Tropical Ocean.

A comparison between Nimbus 5 THIR and ITPR temperatures and derived winds with rawinsonde data obtained in the AVE 2 experiment [PDF]

open access: yes
During the period of May 11 and 12, 1974, NASA conducted its second Atmospheric Variability Experiment (AVE II) over the eastern United States. In this time interval, two Nimbus 5 orbits crossed the AVE II area, providing a series of ITPR soundings as ...

Atmospheric dispersion and the implications for phase calibration [PDF]

open access: yes, 2009
The success of any ALMA phase-calibration strategy, which incorporates phase transfer, depends on a good understanding of how the atmospheric path delay changes with frequency (e.g. Holdaway & Pardo 2001).

Real-Time GNSS-Derived PWV for Typhoon Characterizations: A Case Study for Super Typhoon Mangkhut in Hong Kong

open access: yesRemote Sensing, 2019
Typhoons can be serious natural disasters for the sustainability and development of society. The development of a typhoon usually involves a pre-existing weather disturbance, warm tropical oceans, and a large amount of moisture. This implies that a large

Airborne Lidar measurements of the atmospheric pressure profile with tunable Alexandrite lasers [PDF]

open access: yes, 1986
The first remote measurements of the atmospheric pressure profile made from an airborne platform are described. The measurements utilize a differential absorption lidar and tunable solid state Alexandrite lasers. The pressure measurement technique uses a

401 MHz transistorised radiosonde transmitter

open access: yesMAUSAM, 1992
This paper describes a transistorised radiosonde transmitter which was designed to replace valve version earlier used in national upper air l1etwork for upper air data acquisition. The transmitter operates in 400.6-406 MHz frequency band (tunable) with 500 mill watt power output utilising a 22.5V water activated battery, Stripling technique has been ...

Observations of extremely thin clouds in the tropical tropopause region by a ship based lidar. [PDF]

open access: yes, 2004
During the cruises ANT XVII/4 (Punta Arenas Bremerhaven, 2000) and ANT XX1/1 (Bremerhaven - Cape Town, 2003) continuous measurements of clouds and aerosol have been performed by a Mobile Aerosol Raman Lidar (MARL).

Systematic differences between radiosonde instruments [PDF]

open access: yesGeophysical Research Letters, 2002
Deviations of radiosonde geopotential heights from the zonal mean are examined. In the summer Northern Hemisphere stratosphere, systematic differences are found between radiosonde instrument types. Persistent meridional wind anomalies, approximately constant in magnitude and fixed in location, have previously been reported in the summer stratosphere ...
