Can statistics of turbulent tracer dispersion be inferred from camera observations of SO2 in the ultraviolet? A modelling study [PDF]
Atmospheric Measurement Techniques, 2020 Atmospheric turbulence and in particular its effect on tracer dispersion may be measured by cameras sensitive to the absorption of ultraviolet (UV) sunlight by sulfur dioxide (SO2), a gas that can be considered a passive tracer over short transport ...

REFLECTANCE CALIBRATION SCHEME FOR AIRBORNE FRAME CAMERA IMAGES [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012 The image quality of photogrammetric images is influenced by various effects from outside the camera. One effect is the scattered light from the atmosphere that lowers contrast in the images and creates a colour shift towards the blue.

PFISR nightside observations of naturally enhanced ion acoustic lines, and their relation to boundary auroral features [PDF]
Annales Geophysicae, 2008 We present results from a coordinated camera and radar study of the auroral ionosphere conducted during March of 2006 from Poker Flat, Alaska. The campaign was conducted to coincide with engineering tests of the first quarter installation of the Poker

Rankin Inlet PolarDARN radar observations of duskward moving Sun-aligned optical forms [PDF]
Annales Geophysicae, 2008 On 15 February 2007, several duskward moving sun-aligned (SA) auroral forms have been observed by the all-sky camera at Resolute Bay, Nunavut (Canada). Concurrent observations with the Rankin Inlet (RANK) PolarDARN HF radar within the field-of-view of

THE HALF-YEAR MONITORING OF METEOROID INFLUX TO THE NEAR-EARTH SPACE BY TV-OBSERVATIONS
Odessa Astronomical Publications, 2017 The Astronomical Institute of Russian Academy of Science provides TV-meteor observations since 2000. We began them with hybrid camera for Space Control Survey, but now we use 6 simple wide-angle Patrol Camera (PatrolCa) for every-night monitoring of ...

Monitoring Seedling Emergence, Growth, and Survival Using Repeat High-Resolution Imagery
Remote Sensing, 2022 Environmental factors often limit plant establishment and survival through increased seedling mortality. Understanding plant growth and the causes of mortality can be helpful in developing solutions that enhance seeding success and improve restoration ...

Parameterizing anisotropic reflectance of snow surfaces from airborne digital camera observations in Antarctica [PDF]
The Cryosphere, 2020 The surface reflection of solar radiation comprises an important boundary condition for solar radiative transfer simulations. In polar regions above snow surfaces, the surface reflection is particularly anisotropic due to low Sun elevations and the ...

Remote Sensing, 2019 To improve the accuracy of analysis outputs from remotely sensed images, shadow and illumination effects need to be minimised or removed. Shadow behaviour at different spectral wavelengths needs to be understood to quantify shadow accurately.
