An EARLINET early warning system for atmospheric aerosol aviation hazards
(European Geosciences Union (EGU), 2020-09-15)
Article.
Accés obert
Article.
Accés obert
A stand-alone lidar-based method for detecting airborne hazards for aviation in near real time (NRT) is presented. A polarization lidar allows for the identification of irregular-shaped particles such as volcanic dust and ...
Nodal sampling: a new image reconstruction algorithm for SMOS
(Institute of Electrical and Electronics Engineers (IEEE), 2016-04-01)
Article.
Accés obert
Article.
Accés obert
Soil moisture and ocean salinity (SMOS) brightness temperature (TB) images and calibrated visibilities are related by the so-called G -matrix. Due to the incomplete sampling at some spatial frequencies, sharp transitions ...
SMOS instrument performance and calibration after six years in orbit
(2016-07-01)
Article.
Accés obert
Article.
Accés obert
ESA's Soil Moisture and Ocean Salinity (SMOS) mission, launched 2-Nov-2009, has been in orbit for over 6 years, and its Microwave Imaging Radiometer with Aperture Synthesis (MIRAS) in two dimensions keeps working well. The ...
Compact lidar system using laser diode, binary continuous wave power modulation, and an avalanche photodiode-based receiver controlled by a digital signal processor
(2018-04-18)
Article.
Accés obert
Article.
Accés obert
We analyze the practical limits of a lidar system based on the use of a laser diode, random binary continuous wave power modulation, and an avalanche photodiode (APD)-based photereceiver, combined with the control and ...
Single-pass soil moisture retrievals using GNSS-R: lessons learned
(Multidisciplinary Digital Publishing Institute (MDPI), 2020-06-01)
Article.
Accés obert
Article.
Accés obert
In this paper, an algorithm to retrieve surface soil moisture from GNSS-R (Global Navigaton Satellite System Reflectometry) observations is presented. Surface roughness and vegetation effects are found to be the most ...
L-Band sea surface emissivity: preliminary results of the WISE-2000 campaign and its application to salinity retrieval in the SMOS mission
(2003-06)
Article.
Accés obert
Article.
Accés obert
Soil moisture and ocean salinity at surface level can be measured by passive microwave remote sensing at L-band. To provide global coverage data of soil moisture and ocean salinity with three-day revisit time, the Earth ...
Silicon photomultiplier detector for atmospheric lidar applications
(2012-04-01)
Article.
Accés restringit per política de l'editorial
Article.
Accés restringit per política de l'editorial
The viability and performance of using a silicon photomultiplier (SiPM) in atmospheric lidar applications is experimentally compared against the well-established use of photomultiplier tubes. By using a modified lidar setup ...
Polarization lidar detection of agricultural aerosol emissions
(2018-04-18)
Article.
Accés obert
Article.
Accés obert
Agricultural aerosol emissions can significantly impact human and animal health as well as the environment. Therefore, it is essential to adopt new sensing techniques for real-time monitoring these emissions in high temporal ...
Airborne GNSS-R wind retrievals using delay-doppler maps
