Abstract. In mountainous terrain, the snowpack is strongly affected by incoming shortwave and longwave radiation. In this study, a thorough evaluation of the solar and longwave downwelling irradiance products (DSSF and DSLF) derived from the Meteosat Second Generation satellite was undertaken in the French Alps and the Pyrenees. The satellite-derived products were compared with forecast fields from the meteorological model AROME and with analysis fields from the SAFRAN system. A new satellite-derived product (DSLFnew) was developed by combining satellite observations and AROME forecasts. An ev

Abstract:
A method to separate the active region and quiet network components of the magnetic fields in the photosphere is described and compared with the corresponding measurements of the He I λ 10830 absorption. The relation between the total He I absorption and total magnetic flux in active regions is roughly linear and differs between cycles 21 and 22. There appears to no relation between these two quantities in areas outside of active regions. The total He I absorption in the quiet Sun (comprised of network, filaments, and coronal holes) exceeds that in active regions at all times during the cycle.

Abstract:
In the outer layers of the Sun (≈ 30% by radius), energy is transported by convection. The nature of the highly stratified and compressible convective flow is determined from the components of the energy flux (internal, kinetic, viscous, magnetic and radiative). Local suppressions or enhancements of any of these components may give rise to measurable changes in the emergent radiation.On the solar surface there is direct evidence for modulation of the emerging heat flux covering a large range in spatial and temporal scales, particularly associated with concentrated magnetic fields (e.g. sunspot

Abstract:
Although the light fields and apparent optical properties (AOPs) within the ocean euphotic layer have been studied for many decades through extensive measurements and theoretical modeling, there is virtually a lack of simultaneous high spectral resolution measurements of plane and scalar downwelling and upwelling irradiances (the so-called irradiance quartet). We describe a unique dataset of hyperspectral irradiance quartet, which was acquired under a broad range of environmental conditions within the water column from the near-surface depths to about 80 m in the Gulf of California.

Abstract:
The main cause of variability of solar type stars are their varying magnetic fields. To compute irradiance variations one has to compute the magnetic field (the dynamo problem), and from this the irradiance effects. The second problem is considered here. The theoretical work of the past decade has shown that the dominant effect of magnetic fields is a surface effect: a change of effective emissivity of the magnetic parts of the surface while the nonmagnetic part of the surface contributes very little to the irradiance variation on almost all time scales. No other processes have yet been found

Abstract. Surface solar irradiance variability is present under all broken clouds, but the patterns, magnitude of variability, and driving mechanisms vary greatly with cloud type. In this study, we performed numerical experiments to understand which main mechanisms drive surface solar irradiance (SSI) variations across a diverse set of observation-based cloud conditions. The results show that four mechanisms capture the essence. We find that for optically thin (τ<6) clouds, scattering in the forward direction (forward escape) dominates. In cloud fields with enough optically thin area, such

Representative phototherapy devices are laser surgical instruments and medical laser irradiators.

These medical devices are used under the guidance of healthcare providers in medical institutions and can be hazardous because they use strong light. According to the

Abstract Groundnut (Arachis hypogaea L.), produced in the traditional small-scale rainfed sector of Western Sudan, accounts for 80% of the total annual groundnut acreage, producing 70% of the total production. Low productivity of groundnut is a characteristic feature in North Kordofan State, which is characterized as the most vulnerable state to the impact of climate change. Terminal drought stress resulting from reduction in rainfall amount and distribution at the end of the season is the most deleterious drought period, as it coincides with groundnut pod filling and maturation periods.

Abstract:
A model describing the image irradiance of two images produced by a multiple grating reflection type focusing element is developed. The gratings may be formed simultaneously or sequentially, and the recording medium can change thickness during processing. In the algorithm, the spot size and location of the image are first calculated by ray tracing from each surface grating in the multiplexed grating element. The efficiencies of these rays are then computed with a multiple grating model which allows for coupling between the fields in the grating volume. Finally, the efficiency of each ray is we

Image formation at out-of-focus planes has been the subject of several recent papers that explore the following issues: the focal shift effect, automatic focusing, understanding the properties of 3-D wave fields, and increasing the depth of focus. A simple way to analyze defocused imagery is to employ the Strehl (irradiance) ratio, which is defined as the ratio between the on-axis irradiance of the defocused point spread function (PSF), and the on-axis irradiance of the diffraction-limited PSF. Here, we apply the Strehl (irradiance) ratio to design a spatial filter that increases the depth of

This paper presents a method for the rapid computation of optical electromagnetic fields in optical systems with arbitrarily shaped, smoothly varying surfaces. The method uses the results of a generalized ray tracing routine to provide optical field polarization and wavefront curvature information.

Equations for the approach are written in a form which removes numerical singularities, and groups of equations are written in a format ready for direct computerized lens design applications.

Solar radiation data is necessary for the design of solar heating systems and used to estimate the thermal performance of solar heating plants. Compared to global irradiance, the direct beam component shows much more variability in space and time. The global radiation split into beam and diffuse radiation on collector plane is important for the evaluation of the performance of different collector types and collector field designs.
