Measuring Aerosol Absorption from Omi near Uv Observations
An assessment of OMI retrievals of aerosol properties is presented. We compare OMI retrieved values of extinction and absorption optical depth, and aerosol single scattering albedo to AERONET ground-based measurements. An evaluation of the accuracy of the retrievals for a limited number of observations under cloud-free conditions shows a positive offset of about 0.03 in retrieved optical depth....
متن کاملAssessment of OMI near-UV aerosol optical depth over land
This is the first comprehensive assessment of the aerosol optical depth (AOD) product retrieved from the near-UV observations by the Ozone Monitoring Instrument (OMI) onboard the Aura satellite. The OMI-retrieved AOD by the UV aerosol algorithm (OMAERUV version 1.4.2) was evaluated using collocated Aerosol Robotic Network (AERONET) level 2.0 direct Sun AOD measurements over 8 years (2005–2012)....

متن کاملAerosol Properties from Omi Using the Multi-wavelength Algorithm
The multi-wavelength retrieval algorithm is used to retrieve aerosol parameters from spectra reflectance measurements of the Ozone Monitoring Instrument (OMI). This retrieval algorithm uses up to 19 wavelength bands between 331 nm and 500 nm including a band at 477 nm comprising an absorption band of O2-O2. This absorption band has been included in order to increase the amount of height informa...
متن کاملDetection of Absorbing Aerosol Using Single Near-UV Radiance Measurements from a Cloud and Aerosol Imager
The Ultra-Violet Aerosol Index (UVAI) is a practical parameter for detecting aerosols that absorb UV radiation, especially where other aerosol retrievals fail, such as over bright surfaces (e.g., deserts and clouds). However, typical UVAI retrieval requires at least two UV channels, while several satellite instruments, such as the Thermal And Near infrared Sensor for carbon Observation Cloud an...
