Retrieval of the optical properties of tropospheric aerosols over Athens, Greece combining a 6-wavelength Raman-lidar and the CALIPSO VIS-NIR lidar system: Case-study analysis of a Saharan dust intrusion over the Eastern Mediterranean [PDF]

open access: yes, 2007
The National Technical University of Athens (NTUA) 6-wavelength (355, 387, 407, 532, 607 and 1064 nm) Raman lidar system has been used to derive the aerosol optical properties (e.g. the lidar ratio, the aerosol backscatter and extinction profile) and the

Diurnal Air–Surface Temperature Dynamics in Hong Kong: An Analysis Across Land Use and Climate Zones

open access: yesInternational Journal of Climatology, EarlyView.
Daytime and nighttime air temperature (Ta) from automatic weather stations and land surface temperature (Ts) derived from ASTER and Landsat 8–9 are used to examine the relationship between Ta and Ts. The spatial and statistical characteristics of Ta − Ts dynamics are further analysed across land use (LU) and local climate zones (LCZ).

Detection and Differentiation between Laurel Wilt Disease, Phytophthora Disease, and Salinity Damage Using a Hyperspectral Sensing Technique

open access: yesAgriculture, 2016
Laurel wilt (Lw) is a fatal disease. It is a vascular pathogen and is considered a major threat to the avocado industry in Florida. Many of the symptoms of Lw resemble those that are caused by other diseases or stress factors.

How Well Is Surface Diurnal Temperature Range Represented by Observations at 2‐m Level

open access: yesInternational Journal of Climatology, EarlyView.
We demonstrate that geostationary satellites depict well the Diurnal Temperature Range (DTR) in the US but differ from information at 2 m level from model outputs. Upper: mean diurnal temperature range (DTR) using GOES‐E based land surface temperature (LST) for January (left) and July (right) during 2004–2009. Lower: mean diurnal temperature range (DTR)

Associations between residential greenness, land cover and risk of celiac disease in genetically at‐risk children: Celiac Prediction in Skåne study

open access: yesJournal of Pediatric Gastroenterology and Nutrition, EarlyView.
Abstract Objectives Our aim was to study the association between residential land cover and greenness during childhood and risk of developing celiac disease (CeD). Methods The Celiac Prediction in Skåne study prospectively followed 5969 human leukocyte antigen (HLA)‐genotyped children born 2001–2004 who were screened for CeD at ages 3, 9, and 15 years ...

Characterizing the Spatial Uniformity of Light Intensity and Spectrum for Indoor Crop Production

open access: yesHorticulturae, 2022
Maintaining uniform photon irradiance distribution above the plant canopy is a fundamental goal in controlled environment agriculture (CEA). Spatial variation in photon irradiance below the light saturation point will drive differences in individual ...

Adaptive Display White Point Under Various Ambient Conditions. Part 2: Dual Illumination

open access: yesJournal of the Society for Information Display, EarlyView.
This study was designed to investigate how an adaptive display white point should be adjusted under different foreground‐background illumination conditions. It was found that the background illumination had a more significant effect. ABSTRACT Adaptive displays are designed to enhance the user viewing experience by dynamically responding to ambient ...
