Daily observations of pyranometer network consisting of 50 stations spatially distributed in 3 x 3 square km domain during HOPE-Melpitz campaign.

Daily files of meteorological data (near surface and soil). Stations were located during the HOPE campaign: Station 1 (sebs00) at Hambach together with mets00, Station 2 (sebs01) at Wasserwerk together with mets01.

Pyranometer network consisting of 45 members were set up during the Intensive Observation Campaign at Lindenberg / Falkenberg, 2014.

Daily files of data from pyranometer network (supplemented with a micro-module for RH) consisting of 99 stations spatially distributed in 10 x 12 square km domain during HOPE-Juelich campaign.

The spectral longwave feedback parameter quantifies the change in Earth's spectrally resolved outgoing longwave radiation (OLR) in response to warming. It contains the radiative signature of all longwave feedbacks making it a key quantity influencing Earth's climate sensitivity. By spectrally resolving these changes in OLR, one can gain important information about the underlying feedback processes. This experiment contains spectrally resolved radiative quantities that can be used for the calculation of the global mean all-sky spectral longwave feedback parameter based on seasonal and interannual variability, using both satellite observations and simulations. This dataset was updated to provide more information on the sensitivity of the spectral longwave feedback parameter on relative humidity changes as well as on the impact of the surface feedback at different surface temperatures.

This experiment contains spectrally resolved radiative quantities that can be used for the calculation and interpretation of the global mean all-sky spectral longwave feedback parameter based on seasonal and interannual variability, using both satellite observations and simulations. This is an updated version of the experiment. Compared to the first version, this version contains more data on the sensitivity of the spectral longwave feedback parameter on relative humidity changes. Additionally, this version also contains data on the contribution of the surface feedback for different surface temperatures.
