TL;DR: The Baseline Surface Radiation Network (BSRN) as mentioned in this paper is a new radiometric network, which is designed to provide validation material for satellite radiometry and climate models, and further aims at detecting long-term variations in irradiances at the earth's surface.

TL;DR: In this article, the L to H transition in the DIII-D tokamak is associated with two clear signatures: edge density fluctuations are abruptly suppressed (in ≊100 μsec), while the edge poloidal rotation velocity vθ increases, implying that the radial electric field Er becomes more negative.

TL;DR: In this paper, optical depth measurements from six specific locations and surface irradiance measurements from a large number of radiation sites in Northern Germany and Switzerland were used to confirm solar brightening and show that the direct aerosol effect had an approximately five times larger impact on climate forcing than the indirect aerosol and other cloud effects.

TL;DR: In this paper, the authors investigated the relation between water vapor and LDR and showed how water vapor influences LDR using surface observations, like longwave downward radiation (LDR), surface specific humidity (q) and GPS derived integrated water vapor (IWV), and showed that water vapor not only absorbs solar radiation in the atmosphere but also largely absorbs terrestrial longwave radiation and emits part of it back to the surface.

TL;DR: In this paper, the L-mode to H-mode transition in the DIII-D tokamak is associated with the sudden reduction in anomalous, fluctuation-connected transport across the outer midplane of the plasma.
