Mazzoleni, Claudio; Mazzoleni, Lynn R.; Fialho, Paulo; Kumar, Sumit; Dzepina, Katja; Dziobak, Michael P.; Kramer, Louisa; Olsen, Seth C.; Owen, Robert4th Atmospheric System Research (ASR), Science Team Meeting. Potomac, Maryland, March 18-21, 2013. ; The Pico Mountain Observatory is located at an altitude of 2225 meters above sea level in the summit caldera of the Pico volcano in the Azores, Portugal (38.47°N, 28.40°W). The scientific value of the station stems from the fact that this is the only permanent free-tropospheric monitoring station in the central...

Kramer, Louisa; Mazzoleni, Claudio; Mazzoleni, Lynn R.; Fialho, Paulo; Helmig, Detlev; Olsen, Seth C.; Owen, R. Chris; Dziobak, Michael P.European Geosciences Union (EGU), General Assembly. Viena, Austria, 07 - 12 April 2013. ; Here, we present an overview of gas and aerosol data measured at the Pico Mountain Station. The primary objective of these measurements are to enhance our knowledge of anthropogenic and biomass burning emissions from North America and their relative impact on atmospheric composition and radiative forcing in the free tropo...

Kumar, Sumit; Fialho, Paulo; Mazzoleni, Lynn R.; Olsen, Seth C.; Owen, R. Chris; Helmig, Detlev; Hueber, Jacques; Dziobak, Michael P.; Kramer, Louisa45th annual Fall Meeting, AGU. San Francisco, California, 3-7 December. ; The Pico Mountain Observatory is located in the summit caldera of the Pico mountain, an inactive volcano on the Pico Island in the Azores, Portugal (38.47°N, 28.40°W, Altitude 2225m asl). The Azores are often impacted by polluted outflows from the North American continent and local sources have been shown to have a negligible influence a...

Mazzoleni, Claudio; Fialho, Paulo; Gorkowski, Kyle; Owen, Robert; Dziobak, Michael P.; Hueber, Jacques; Dzepina, Katja; Kramer, Louisa; Olsen, Seth C.3th Atmospheric Science Research (ASR), Science Team Meeting. Arlington, Virginia, March 12-16, 2012. ; Pico is a small island (447 km2) in the archipelago of the Azores, Portugal, in the North Atlantic Ocean. The island has a very steep inactive volcano. An atmospheric monitoring station (Pico Mountain Observatory) was established close to the summit of the volcano by the late Dr. Richard Honrath and colleagu...
Free Tropospheric Aerosol Measurements at the Pico Mountain Observatory, Azores...
Mazzoleni, Claudio; Mazzoleni, Lynn R.; Fialho, Paulo; Kumar, Sumit; Dzepina, Katja; Dziobak, Michael P.; Kramer, Louisa; Olsen, Seth C.; Owen, RobertAAAR 31st Annual Conference. Minneapolis, Minnesota, October 8-12, 2012. ; In this poster we discuss a limited subset of the aerosol measurements performed at the Pico Mountain Observatory. The Black Carbon (BC) mass shows a clear seasonal pattern over a ten-years period. The 2012 scattering measurements show highly variable signals with events with high scattering and periods of very low aerosol loading. Dust...

Dzepina, Katja; Kumar, Sumit; Mazzoleni, Claudio; Fialho, Paulo; Dziobak, Michael P.; Hueber, Jacques; Helmig, Detlev; Kramer, Louisa; Olsen, Seth C.AAAR 31st Annual Conference. Minneapolis, Minnesota, October 8-12, 2012. ; The Pico Mountain Observatory is located at 2225 m amsl on an inactive volcano at Pico Island in the Azores archipelago in the North Atlantic ~3900 km east and downwind of North America (38º28'15''N; 28º24’'14''W). The unique location of the Observatory enables sampling of free tropospheric air transported over long, intercontinental di...
A permanent free tropospheric observatory at Pico summit in the Azores Islands?...
Honrath, Richard; Fialho, Paulo; Helmig, Detlev; Val Martin, Maria; Owen, Robert; Kleissl, J.; Strane, J. M.; Dziobak, Michael P.; Tanner, D. M.AGU Fall Meeting. San Francisco, California, 5-9 December 2005. ; Pico mountain in the Azores Islands provides a base for continuous, free tropospheric measurements that is unique in the central North Atlantic region. The PICO-NARE station was installed there in 2001 as a temporary observatory. However, the location proved ideal for studies of aged emissions from anthropogenic (N. American) and boreal fire (N....
Regional and hemispheric impacts of anthropogenic and biomass burning emissions...
Honrath, Richard; Owen, R. Chris; Val Martin, Maria; Reid, J. S.; Lapina, K.; Fialho, Paulo; Dziobak, Michael P.; Kleissl, J.; Westphal, D. L.Copyright © 2004 American Geophysical Union. All Rights Reserved. ; We report summertime measurements of CO and O3 obtained during 2001–2003 at the PICO-NARE mountaintop station in the Azores. Frequent events of elevated CO mixing ratios were observed. On the basis of backward trajectories arriving in the free troposphere and global simulations of biomass burning plumes, we attribute nearly all these events to...
