A GPS-based Three-Dimensional Lightning Mapping System: Initial Observations in Central New Mexico

A GPS-based system has been developed that accurately locates the sources of VHF radiation from lightning discharges in three spatial dimensions and time. The observations are found to re ect the basic charge structure of electri ed storms. Observations have also been obtained of a distinct type of energetic discharge referred to as positive bipolar breakdown, recently identi ed as the source o...

Monitoring of SO2 column concentration over Iran using satellite-based observations during 2005-2016

For the first time, sulfur dioxide concentration was monitored between 2005 and 2016 over Iran which is among the countries with a high SO2 emission rate in the world. To that end, SO2 column concentration at Planetary Boundary Layer (PBL) from Ozone Monitoring Instrument (OMI) was analyzed. OMI is a sensor onboard the Aura satellite which can measure daily SO2 concentration on the global scale...

Aerosol Optical Properties of a Haze Episode in Wuhan Based on Ground-Based and Satellite Observations

A severe haze episode that occurred in Wuhan, central China, from 6–14 June 2012 was investigated using ground-based and satellite-derived observations, from which the optical properties and vertical distribution of the aerosols were obtained. The mass concentrations of PM2.5 and black carbon (BC) were 9.9 (332.79 versus 33.66 μg·m) and 3.2 times (9.67 versus 2.99 μg·m) greater, respectively, o...
