2 project summary
2. Project Summary

Use operational MODIS, GOES Aerosol Optical Depth (AOD) products, and OMI/GOME-2 Aerosol Index (AI) to provide near-real-time air quality monitoring and nowcasts. Research and development work done under this project will investigate the usefulness of satellite measurements in improving air quality forecasts and pave the way for using enhanced aerosol products from GOES-R ABI

Operational GOES AOD, MODIS AOD, OMI/GOME-2 AI data

GOES-R ABI like retrievals obtained from MODIS radiances


Develop a new component in IDEA product

Develop and evaluate new GOES AOD retrieval algorithm (MAIAC)

Expected Outcome

Improved IDEA product

Implementation of the new GOES AOD algorithm into IDEA

Demonstration of improved air quality predictions


3 motivation justification
3. Motivation/Justification

Supports NOAA Mission Goal(s):

Weather and water

GOES-R ABI aerosol products will support Memorandum of Understanding (MOU) and Memorandum of Agreement (MOA) between EPA and NOAA

Current GOES aerosol products have limitations. Only AOD retrieval from a single channel is possible. Retrieval has uncertainties associated with surface reflectance retrieval and other assumptions. GOES-R ABI aerosol products are expected to be of better quality than current GOES.

Although there are more than six hundred surface PM2.5 (particles smaller than 2.5 microns in diameter) stations over North America, there are large areas without measurements between stations and there are no measurements over the ocean. Satellite derived column AOD measurements correlate with surface PM2.5 and can be used to fill in the gaps and provide contiguous estimation of PM2.5.

4 methodology
4. Methodology

New IDEA component

Develop aerosol winds for nowcasting applications by replacing current IDEA trajectory forecasts with winds derived from aerosol imagery

New GOES AOD retrieval algorithm (MAIAC)

Image registration, this is to reduce the shift found in GOES images due to the jitter of the satellite so that the pixels with same geolocations from different images are co-located within one pixel error

Project MODIS 2.12 um channel BRDF on GOES grid.

Assume GOES channel 1 BRDF is proportional to MODIS 2.12 m channel, retrieve AOD using MAIAC algorithm

Evaluate the AOD and surface reflectance retrievals by comparing to the results from AERONET, MODIS, GASP, etc.

7 fy08 accomplishments
7. FY08 Accomplishments

Improved IDEA by Including additional satellite aerosol data in the IDEA system

MODIS Aqua AOD, an individual tab with all the five products

OMI AI, incorporated in the Aqua trajectory forecast so that trajectories are initiated at level where OMI AI are high


Comparison of OMI and GOME-2 Aerosol Index (AI) product

Developed GOES image registration method to prepare for the new AOD retrieval algorithm

Major findings

On average, GOME-2 AI is larger than OMI AI over most regions for absorbing aerosols, and is smaller for scattering aerosols

The GOES channel 1 images shift due to the satellite jitter. We use image registration to reduce this shift to less than 1 pixel.
