Measurement of volcanic ash in Norwegian air space. WP 1.4.4 Reduced uncertainty in satellite-based estimates of ash concentrations. NILU OR

Kylling, A.

Satellite-based measurements of volcanic ash give the total amount of volcanic ash per area, typically in units of grams of volcanic ash per square meter. To convert this to concentration the vertical thickness of the ash cloud is needed. The ash cloud thickness is not available from passive remote sensors, e.g. IR-sensors, but may be obtained from ground- and space-based lidars. Dispersion models will also provide information of the ash thickness.
This report gives an overview of volcanic ash cloud thickness as observed by space, aircraft and ground-based lidars. Also, ash cloud thickness as simulated by the Flexpart particle dispersion model is analysed. The impact of varying cloud thickness on the signal measured by IR-sensor in space is investigated. Focus is on the Eyjafjallajokull 2010 eruption for which a unique wealth of data are available.

Review of ambient air quality monitoring programme in Poland. NILU OR

Bøhler, T.; Guerreiro, C.; Marsteen, L.

The Norwegian Institute for Air Research - NILU and the Chief Inspectorate of Environmental Protection - GIO¿ are implementing the project : 'Strengthening the air quality assessment system in Poland, based on Norwegian experience' as part of the programme ¿Improving Environmental Monitoring and Inspection¿ within the framework of the European Economic Area 2009-2014.
A part of this project is to review the existing ambient air quality monitoring programme in operation in Poland based upon the report prepared by GIOS: ¿Information on monitoring equipment used in Voivodeship networks within the National Environmental Monitoring and supplementary data providing grounds for network equipment analyses¿.
The NILU assessment confirms the needs described by GIOS to carry out an intensive monitoring of air quality, especially as regards PM10, PM2.5, benzo(a)pyrene and ozone. NILU advices GIOS to include the modelling results when evaluating the needs for expanding the network for ozone.NILU recommends to evaluate the needs for further stations in relation to securing the data capture rate as requested by the EU Directive.
In general, NILU advices GIOS towards having a more robust network that meets the Directive requirements regarding data coverage and ensures enough information for the WIOSs to do assessment and planning.
