Fifteen Years of HFC‐134a Satellite Observations: Comparisons With SLIMCAT Calculations

Arctic ozone loss deduced from POAM III satellite observations and the SLIMCAT chemical transport model

The SLIMCAT three-dimensional chemical transport model (CTM) is used to infer chemical ozone loss from Polar Ozone and Aerosol Measurement (POAM) III observations of stratospheric ozone during the Arctic winter of 2002–2003. Inferring chemical ozone loss from satellite data requires quantifying ozone variations due to dynamical processes. To accomplish this, the SLIMCAT model was run in a “pass...

Fifteen Years (1993–2007) of Surface Freshwater Storage Variability in the Ganges-Brahmaputra River Basin Using Multi-Satellite Observations

Surface water storage is a key component of the terrestrial hydrological and biogeochemical cycles that also plays a major role in water resources management. In this study, surface water storage (SWS) variations are estimated at monthly time-scale over 15 years (1993–2007) using a hypsographic approach based on the combination of topographic information from Advance Spaceborne Thermal Emission...

Spatial variation of aerosol properties over Europe derived from satellite observations and comparison with model calculations

Aerosol optical depths (AOD) and Angström coefficients over Europe were retrieved using data from the ATSR-2 radiometer on board the ESA satellite ERS-2, for August 1997. Taking advantage of the nadir and forward view of the ATSR-2, the dual view algorithm was used over land to eliminate the influence of the surface reflection. Over sea the AOD was retrieved using only the forward observations....

Fifteen Years to Open Source

You can’t change an organization, states the rst rule of change management, unless that organization can be changed. More to the point: you can’t change an organization unless its structure lets you promulgate new policies, implement those policies, and assess their outcome. While this idea might seem self-evident, it has been the shoal on which many companies have foundered. It’s also the key ...
