Spatial distribution interannual variation eighty-six Chinese cities
font style='font-size:12px;'>
2010/8/13
The spatial distribution of the aerosols over 86 Chinese cities was reconstructed from air pollution index (API) records for summer 2000 to winter 2006. PM10 (particulate matter ≤10 μm) mass concentra...
Source attribution and interannual variability of Arctic pollution in spring constrained by aircraft (ARCTAS, ARCPAC) and satellite (AIRS) observations of carbon monoxide
Arctic pollution spring constrained ARCTAS carbon monoxide

2010/2/21
We use aircraft observations of carbon monoxide (CO) from the NASA ARCTAS and NOAA ARCPAC campaigns in April 2008 together with multiyear (2003–2008) CO satellite data from the AIRS instrument and a g...
Influence of meteorological variability on interannual variations of springtime boundary layer ozone over Japan during 1981–2005

Two 40-year meteorological datasets are used to drive the Model of Ozone and Related Tracers chemical transport model, version 2 (MOZART2) in hindcast simulations. One dataset is from the National Cen...
SCIAMACHY CO over land and oceans: 2003–2007 interannual variability
SCIAMACHY CO land oceans

2009/6/16
We present a new method to obtain accurate SCIAMACHY CO columns over clouded ocean scenes. Based on an improved version of the Iterative Maximum Likelihood Method (IMLM) retrieval algorithm, we now ha...
Transport mechanisms for synoptic, seasonal and interannual SF6 variations and“age”of air in troposphere
Transport mechanisms synoptic seasonal interannual SF6 variations troposphere
