10-year satellite-constrained fluxes of ammonia improve performance of chemistry transport models
(Peer reviewed; Journal article, 2021)In recent years, ammonia emissions have been continuously increasing, being almost 4 times higher than in the 20th century. Although an important species, as its use as a fertilizer sustains human living, ammonia has major ... -
The 11 year solar cycle UV irradiance effect and its dependency on the Pacific Decadal Oscillation
(Peer reviewed; Journal article, 2021)The stratospheric, tropospheric and surface impacts from the 11 year ultraviolet solar spectral irradiance (SSI) variability have been extensively studied using climate models and observations. Here, we demonstrate using ... -

A COMPARISON OF MEASUREMENTS WITH ISO REFERENCE AND NILU ATMOSPHERIC DUSTFALL DEPOSIT GAUGES.
(NILU TR; 9/85, Research report, 1985)Atmospheric dustfall deposit measured with the ISO reference gauge and the NILU gauge have been compared. Only water insoluble deposit was considered. The NILU gauge gave somewhat higher deposit values than the ISO gauge, ... -

A DISPERSION MODEL FOR INTERREGIONAL AIR POLLUTION PROBLEMS
(NILU TN;1/81, Research report, 1981)The time variation in concentration in three levels is considered by describing: a) advection, b) vertical exchange, c) horizontal diffusion, d) chemical reactions, e) emission from natural and antropogenic sources. Dry ... -
A DPSIR-analysis of water uses and related water quality issues in the Colombian Alto and Medio Dagua Community Council
(Journal article; Peer reviewed, 2018)A portion of Colombia’s water resources is located on the Pacific coast within the territory of the Community Council of Alto and Medio Dagua (CC-AMDA). Though a harmonious balance between the communities’ subsistent ... -
