MAREDAT: towards a world atlas of MARine Ecosystem DATa
(2012)Earth System Science Data DiscussionsWe present a summary of biomass data for 11 Plankton Functional Types (PFTs)plus phytoplankton pigment data, compiled as part of the MARine Ecosystem biomassDATa (MAREDAT) initiative. The goal of the MAREDAT initiative is to provide global gridded data products with coverage of all biological components of the global ocean ecosystem. This special issue is the first step towards achieving this. The PFTs presented here include picophytoplankton, ...Working Paper -
Computational snow avalanche simulation in forested terrain
(2013)Natural Hazards and Earth System Sciences DiscussionsTwo-dimensional avalanche simulation software operating in three-dimensional terrainis widely used for hazard zoning and engineering to predict runout distances andimpact pressures of snow avalanche events. Mountain forests are an effective biologicalprotection measure; however, the protective capacity of forests to decelerate or even to stop avalanches that start within forested areas or directly above the treeline isseldom considered ...Working Paper -
Can we reconstruct Arctic sea ice back to 1900 with a hybrid approach?
(2008)Climate of the Past DiscussionsThe variability and trend of Arctic sea ice since the mid 1970s is well documented and linked to rising temperatures. However, much less is known for the first half of the 20th century, when the Arctic also underwent a period of strong warming. For studying this period in atmospheric models, gridded sea ice data are needed as boundary conditions. Current data sets (e.g., HadISST) provide a historical climatology, but may not be suitable ...Working Paper -
Radiation transfer in stratus clouds at the BSRN Payerne site
(2008)Atmospheric Chemistry and Physics DiscussionsClouds represent a major source of uncertainty in understanding climate change, because potential changes in the way they affect the atmospheric and surface energy budget are difficult to predict. It is therefore important to determine how clouds affect radiation. Stratiform clouds in particular have an important effect on climate as they cover large areas. This article presents results of radiation transfer calculations with MODTRANTM ...Working Paper
