Effect of smoke on the transmissivity of photosynthetically active radiation inside the canopy

, 2005
International audienceBiomass burning activities emit high concentrations of aerosol particles to the atmosphere. Such particles can interact with solar radiation, decreasing the amount of light reaching the surface and increasing the fraction of diffuse

Visual Patterns of Diaphragmatic Motion in Acute Respiratory Failure: A Prospective Pilot Study

Journal of Clinical Ultrasound, Volume 53, Issue 3, Page 421-428, March/April 2025.
In this prospective bicentric study, we studied the relationship between the appearance of diaphragmatic motion and the etiological diagnosis of patients admitted to the emergency department with ARF. We observed a different visual pattern in patients with pneumonia. This is an interesting result as it allows the diagnosis of pneumonia without the need

Error Propagation From Aerosol Retrieval to Atmospheric Correction Due to Adjacency Effect for FORMOSAT-2 RSI Band

Terrestrial, Atmospheric and Oceanic Sciences, 2007
Homogeneous surface is usually assumed in aerosol retrieval for the dark target method. Retrieved aerosol optical depth can thus be overestimated.

Lidar Ratios for Dust Aerosols Derived From Retrievals of CALIPSO Visible Extinction Profiles Constrained by Optical Depths from MODIS-Aqua and CALIPSO/CloudSat Ocean Surface Reflectance Measurements [PDF]

, 2010
CALIPSO's (Cloud Aerosol Lidar Infrared Pathfinder Satellite Observations) analysis algorithms generally require the use of tabulated values of the lidar ratio in order to retrieve aerosol extinction and optical depth from measured profiles of attenuated

Seasonal Variability of Precipitating Systems in Four Radar Domains of Northeast Brazil

International Journal of Climatology, EarlyView.
This study analyzes the climatology and evaluates how the physical aspects of precipitating systems are influenced by the dry and wet seasons in Northeast Brazil, highlighting seasonal variations in the frequency, size, intensity, and duration of these systems in the regions of Natal, Maceió, Petrolina, and Salvador.

Optical Model of Atmospheric Aerosols in Russian Siberia for Correction of Satellite Data [PDF]

, 1998
Atmospheric components (aerosols and molecules) scatter and absorb solar radiation. They significantly influence the contrast and apparent resolution of satellite images of the Earth's surface taken in the visible and near infrared spectral channels. For

A Measurement of Time-Averaged Aerosol Optical Depth using Air-Showers Observed in Stereo by HiRes

, 2006
Air fluorescence measurements of cosmic ray energy must be corrected for attenuation of the atmosphere. In this paper we show that the air-showers themselves can yield a measurement of the aerosol attenuation in terms of optical depth, time-averaged over

Demonstration, validation, and application of hyperspectral microscopy for the collection of cyanobacterial spectral signatures

Limnology and Oceanography: Methods, EarlyView.
Abstract Cyanobacterial and other algal blooms are an environmental concern in waterbodies worldwide. While these blooms are a nuisance for recreational activities, they can also be harmful to human and wildlife health when the algae produce and release toxins.
