Peroxyacetic acid (PAA) is one of the most important atmospheric organic peroxides, which have received increasing attention for their potential contribution to the oxidation capacity of the troposphere and the formation of secondary aerosols. We report here, for the first time, a series of data for atmospheric PAA concentrations at urban and rural sites,(More)
In this study, typhoon eyes have been delineated using wavelet analysis from the synthetic aperture radar (SAR) images of ocean surface roughness and from the warm area at the cloud top in the infrared (IR) images, respectively. Envisat SAR imagery, and multi-functional transport satellite (MTSAT) and Feng Yun (FY)-2 Chinese meteorological satellite IR(More)
Concurrent Level-3 data products from MERIS, MODIS, and SeaWiFS between June 2003 and June 2006 for the East China Seas were compared against each other to evaluate the consistency between the sensors. The atmospheres in these regions is generally turbid, with typical aerosol optical thickness at 865 nm (tau_865) around 0.16, therefore presents a challenge(More)
Detection of red tides (harmful algal blooms or HABs) from space has been problematic in optically complex waters, mainly due to interference from non-pigment constituents to the satellite signal. Using in situ and MERIS (Medium Resolution Imaging Spectrometer) measurements, the spectral characteristics of red tide and non-red tide waters were studied in(More)
