HALOGAS: HI Observations and Modeling of the Nearby Edge-on Spiral Galaxy NGC 4244
HALOGAS: HI Observations Modeling Nearby Edge-on Spiral
2011/10/12
We present 21-cm observations and models of the HI kinematics and distribution of NGC 4244, a nearby edge-on Scd galaxy observed as part of the Westerbork Hydrogen Accretion in LOcal GAlaxieS (HALOGAS...
Coronal Loops: Observations and Modeling of Confined Plasma
Coronal Loops Observations Confined Plasma
2011/1/13
Coronal loops are the building blocks of the X-ray bright solar corona. They owe their brightness to the dense confined plasma, and this review focuses on loops mostly as structures confining plasma. ...
On microphysical processes of noctilucent clouds (NLC): observations and modeling of mean and width of the particle size-distribution
noctilucent clouds the particle size-distribution
2010/8/16
Noctilucent clouds (NLC) in the polar summer mesopause region have been observed in Norway (69° N, 16° E) between 1998 and 2009 by 3-color lidar technique. Assuming a mono-modal Gaussian size distribu...
Satellite observations and modeling of transport in the upper troposphere through the lower mesosphere during the 2006 major stratospheric sudden warming
Satellite observations upper troposphere lower mesosphere major stratospheric sudden warming
2009/7/23
An unusually strong and prolonged stratospheric sudden warming (SSW) in January 2006 was the first major SSW for which globally distributed long-lived trace gas data are available covering the upper t...
Satellite Observations and Modeling of Meanders in the California Current System off Oregon and Northern California
Satellite Observations California Current System Northern California
2009/1/21
Infrared satellite images from the west coasts of Oregon and northern California are used to identify meander patterns in sea surface temperature which appear as large cold tongues extending offshore....
Observations and Modeling of Wind-driven Currents in the Northeast Pacific
Wind-driven Currents Northeast Pacific Velocity measurements
2008/12/17
Velocity measurements from the interior of the Alaskan gyre are presented from a current meter mooring deployed in 4000 m of water at 49°33′N, 138°38′W, in the vicinity of Ocean Weather Station P. The...
In-situ observations and modeling of small nitric acid-containing ice crystals
In-situ observation nitric acid-containing ice crystals
2008/12/12
Measurements in nascent ice forming regions are very rare and help understand cirrus cloud formation and the interactions of trace gases with ice crystals. A tenuous cirrus cloud has been probed with ...
Near-source observations and modeling of the Kuril Islands tsunamis of 15 November 2006 and 13 January 2007
Near-source observations Kuril Islands tsunamis 15 November 2006 13 January 2007
2010/1/27
Two major earthquakes near the Central Kuril Islands (Mw=8.3 on 15 November 2006 and Mw=8.1 on 13 January 2007) generated trans-oceanic tsunamis recorded over the entire Pacific Ocean. The strongest o...
In situ pCO2 and O2 measurements in a lake during turnover and stratification: Observations and modeling
pCO2 O2 measurements lake during turnover stratification Observations and modeling
2014/5/14
Sensors for the partial pressure of CO2 (pCO2) and dissolved O2 (DO) were deployed near the surface and bottom of a freshwater lake (Placid Lake, Montana) during the period from ice cover to seasonal ...
