An ‘Ionospheric Weather’ Index [PDF]

open access: yesGeophysical Journal of the Royal Astronomical Society, 2010
This note explains a method for deriving a daily ' ionospheric weather ' index for a given geographic location, and displays the behaviour of this index for the Boulder ionosphere during 8 months of 1968. ' Ionospheric weather ' means the dynamic state of the ionosphere at a particuIar time and place, as influenced by the number and intensity of ...

Weathering, atmospheric deposition and vegetation uptake: role for ecosystem sensitivity to acid deposition and critical load [PDF]

open access: yes, 2004
Critical loads of acidity represent the maximum acceptable atmospheric deposition for an ecosystem type. Two hundred and forty-one ecosystem types have been defined in France using pedologic, geologic and vegetation data.

Silicate rock weathering and atmospheric/soil CO2 uptake in the Amazon basin estimated from river water geochemistry: seasonal and spatial variations [PDF]

open access: yes, 2003
Using the data of the CAMREX project (1982–1984) on the water geochemistry of the Amazon river and its main tributaries, it was possible to assess the silicate rock weathering processes and the associated consumption of atmospheric/soil CO2, taking into
