Technical Note: Propagating correlations in atmospheric inversions using different Kalman update smoothers
atmospheric Kalman update smoothers Technical Note
2011/2/25
The scheme to propagate correlations between on-line and off-line state variables in atmospheric inversions using the fixed-lag Kalman smoother proposed in Bruhwiler et al. (2005) is explained as a pr...
Correlations of mesospheric winds with subtle motion of the Arctic polar vortex
mesospheric winds subtle motion Arctic polar vortex
2010/2/1
This paper investigates the relationship between high latitude upper mesospheric winds and the state of the stratospheric polar vortex in the absence of major sudden stratospheric warmings. A ground b...
Nonlinear correlations of daily temperature records over land
Nonlinear correlations daily temperature records
2009/11/9
We present a near global statistics on the correlation properties of daily temperature records. Data from terrestrial meteorological stations in the Global Daily Climatology Network are analyzed by me...
Long term measurements of submicrometer urban aerosols: statistical analysis for correlations with meteorological conditions and trace gases
submicrometer urban aerosols meteorological conditions trace gases
2009/3/11
Long-term measurements (over 4 years) of particle number size distributions (submicrometer particles, 3-800 nm in diameter), trace gases (NO, NO2, and O3), and meteorological parameters (global radiat...
Ozone production and trace gas correlations during the June 2000 MINATROC intensive easurement campaign at Mt. Cimone
Ozone production trace gas correlations MINATROC intensive easurement campaign Mt. Cimone
2009/3/10
An intensive measurement campaign was performed in June 2000 at the Mt. Cimone station (44°11' N-10°42' E, 2165 m asl, the highest mountain in the northern Italian Apennines) to study photochemical oz...
Ozone loss and chlorine activation in the Arctic winters 1991-2003 derived with the tracer-tracer correlations
Ozone loss chlorine activation Arctic winters tracer-tracer correlations
2009/3/9
Chemical ozone loss in the Arctic stratosphere was investigated for the twelve years between 1991 and 2003 employing the ozone-tracer correlation method. For this method, the change in the relation be...
Aerosol-ozone correlations during dust transport episodes
Aerosol-ozone dust transport episodes
2009/3/3
Its location in the Mediterranean region and its physical characteristics render Mt. Cimone (44°11′ N, 10°42′ E), the highest peak of the Italian northern Apennines (2165 m asl), particularly suitable...
Neural networks are ideally suited to describe the spatial and temporal dependence of tracer-tracer correlations. The neural network performs well even in regions where the correlations are less compa...
