Jump to: navigation, search

Welcome to the October 2012 newsletter of the NASA Air Quality Applied Sciences Team (AQAST). AQAST is a team of atmospheric scientists focused on serving air quality management needs through the use of Earth Science data and tools. We conduct a wide range of projects in partnership with air quality agencies at the local, state, regional, and national levels.

This newsletter keeps you up to date on AQAST publications, activities, and events. The AQAST website has more detailed information on ongoing projects. See in particular the list of new Year 2 Investigator Projects. We welcome input from air quality managers. If you would like to propose a project to AQAST, contact any AQAST member or team leader Daniel Jacob.

The next AQAST meeting will be held on November 29-30, 2012 at the California Air Resources Board in Sacramento. The meeting is open and all are welcome to attend. See below for more information.

AQAST meetings

We hope to see you at the following upcoming AQAST events:

4th biannual AQAST meeting, Nov 29-30 2012

The 4th biannual AQAST meeting will be held on Nov 29-30 2012 at the California Air Resources Board in Sacramento. Our hosts will be Bart Croes, Eileen McCauley, and Peter Mathews of CARB. The goal of the meeting will be to share the latest results from AQAST and related activities, and to discuss current air quality issues facing California and the West. Day 1 will consist of short results-oriented talks by AQAST members and other Earth scientists engaged in air quality applications. Day 2 (morning) will consist of presentations by air quality managers followed by open discussion with focus on how AQAST may be of service. Day 2 (afternoon) will consist of AQAST breakout, recap, and action-item sessions. You can find more information including logistics on the meeting website.

The meeting is free and open to all. We particularly encourage the participation of air quality managers on Day 1 and morning of Day 2. You will need to register on the meeting web site. Registration is quick and easy. It will put you on the email list for more information about the meeting.

A detailed agenda for the meeting will be forthcoming and sent to the registration list. To get a feel for the content of AQAST meetings, please browse through the agenda of our 3rd biannual meeting in Madison, WI (June 14-15) including links to presentations.

AQAST session at the Fall 2012 AGU meeting

AQAST is organizing a special session, "Application of satellite data to serve air quality management needs (A008)", at the Fall 2012 meeting of the American Geophysical Union in San Francisco on December 3-7. We will have 69 presentations spread over four oral sessions on Monday December 3 and a poster session on the morning of Tuesday December 4.

AQAST Town Hall at the Fall 2012 AGU meeting

In addition to the AQAST sessions, there will be an AQAST Town Hall at the AGU on Monday December 3 from 12:30 to 1:30. At this Town Hall we will give a brief overview of AQAST, to be followed by an open future-oriented discussion on AQAST directions and partnerships. We hope to have strong participation in this Town Hall of both air quality managers and Earth Scientists interested in air quality applications.

Other AQAST activities

The Saint Louis Ozone Garden: an education/outreach component of AQAST, by Jack Fishman

AQAST members Jack Fishman and Kelley Ballina(Saint Louis University) have developed The St. Louis Ozone Garden Project as a collaborative effort led by Saint Louis University’s Center for Environmental Sciences (CES), the Missouri Botanical Garden, and the Saint Louis Science Center. It is intended to be the prototype garden for AQAST that will serve as a display that demonstrates the impact of degraded air quality on the planet’s living biota. In future years, it is envisioned that similar gardens will be planted at other locations around the country, with other members of the AQAST forming partnerships with their own local Science Centers and/or Botanical Gardens. Here is the first-year summary on this project.

User-friendly processing of OMI NO2, MOPITT CO, and MODIS AOD data, by Tracey Holloway

The Wisconsin Horizontal Interpolation Program for Satellites (WHIPS software developed by AQAST member Tracey Holloway's group at the University of Wisconsin-Madison aggregates Level-2 OMI NO2 (NASA or KNMI), MOPITT CO, or - new! - MODIS AOD data to any user-defined grid and temporal averaging period. The software is free and publicly available. The open-source Python-based algorithms allow further user modifications as needed. These flexible scripts support the comparison of satellite data and regional air quality models, and comparison among satellite data products by converting results to a common grid.

GEO-CAPE publication and website, by Jack Fishman

The GEO-CAPE geostationary satellite mission for air quality in North America is part of the cohorte of Decadal Survey missions planned by NASA over the next decade. A detailed mission overview is presented in this recently published paper by lead author and AQAST member Jack Fishman:
