Recent studies indicate that the Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP) aboard and Infrared Pathfinder Satellite Observations (CALIPSO) satellite provides valuable information about ocean phytoplankton distributions. CALIOP’s attenuated backscatter coefficients, measured at 532 nm in receiver channels oriented parallel perpendicular to laser’s linear polarization plane, are s...
[1] The signature of the stratospheric Brewer-Dobson circulation (BDC) in tropospheric cloudiness is investigated in CloudSat and CALIPSO data from June 2006 through April 2011. During the Northern Hemisphere winter, periods of enhanced stratospheric wave driving are associated with increased cloud incidence in the tropical tropopause transition layer (TTL) juxtaposed against decreased cloud in...
Abstract The longest cirrus time series are ground-based, visual observations captured by human observers (SYNOP). However, their reliability is impacted an unfavourable viewing geometry (cloud overlap), and misclassification due to low cloud optical thickness, especially at night. For the very first time, this study assigns a quantitative value uncertainty. We validate 15 years of SYNOP (2006–...
Lidar and radar observations from CALIPSO and CloudSat missions have allowed the development of methods to determine atmospheric parameters [1, 2]. Total aerosol optical depth (AOD) and cloud liquid water path have thus been derived at the scale of the lidar or radar footprint using AMSR-E wind speed information [3, 4], or the combination of lidar and radar observations using ocean surface echo...
The Earth Clouds, Aerosols and Radiation Explorer, EarthCARE, has been selected for implementation as the sixth Earth Explorer Mission of the European Space Agency’s Living Planet Programme [1]. The mission will measure three-dimensional structures of clouds and aerosols simultaneously with the respective outgoing broad band flux. These measurements would significantly contribute to the underst...
Transnational access (TNA) to national radiation sources is presently provided via programmes of the European Commission by BIOSTRUCT-X and CALIPSO with a major benefit for scientists from European countries. Entirely based on scientific merit, TNA allows all European scientists to realise synchrotron radiation experiments for addressing the Societal Challenges promoted in HORIZON2020. In addit...
