Hyperspectral remote sensing reflectance (Rrs) derived from PRISMA in the visible and infrared range was evaluated for two inland coastal water sites using above-water situ measurements autonomous hyper- multispectral radiometer systems. We compared Level 2D (L2D) surface reflectance, a standard product distributed by Italian Space Agency (ASI), as well outputs ACOLITE/DSF, now adapted processi...

We have started a light pollution survey in the Hungarian national parks. use mobile laboratory consisting of digital cameras and robotic panorama heads to gather high-resolution imaging radiometry. The same type with fish-eye lenses are used fix monitoring stations. Parallel radiometry, we measure spectral distribution sky radiation. spectroradiometry provides additional calibration check on m...

Frequency-domain infrared photothermal radiometry is introduced as a dynamic dental diagnostic tool and its main features are compared with modulated laser luminescence for quantifying sound and carious enamel or dentin. Dental caries found in the fissures or grooves of teeth is very difficult to diagnose or quantify with the present clinical techniques. Visual examination and dental radiograph...

The thickness of oil spills on the sea is an important but poorly studied topic. Means to measure slick thickness are reviewed. More than 30 concepts are summarized. Many of these are judged not to be viable for a variety of scientific reasons. Two means are currently available to remotely measure oil thickness, namely, passive microwave radiometry and time of acoustic travel. Microwave radiome...

MERITXELL is a ground-based multisensor instrument that includes a multiband dual-polarization radiometer, a GNSS reflectometer, and several optical sensors. Its main goals are twofold: to test data fusion techniques, and to develop Radio-Frequency Interference (RFI) detection, localization and mitigation techniques. The former is necessary to retrieve complementary data useful to develop geoph...
