EVENTS AND TESTIMONIALS
Dr. Pamela Ellis
Executive Director
Books Motivate Foundation, Inc.
On behalf of the Advisory Board of Books Motivate Foundation, and our guests, we extend our sincere gratitude for your climate presentation, Tipping Points in the Climate System. Your exemplary level of dedication to high standards of excellence in research, teaching, and community service during the 2019 National Climate Outreach Program, Breakfast of Champions event held on August 31, 2019, in Washington, D.C. was very much appreciated by all in attendance. We certainly hope to have opportunity to work more with you in the future with regard to our mutual climate crisis concerns.

THE ADVANCED NATIONAL AIR QUALITY FORECASTING CAPABILITY (NAQFC)
NOAA Upgrades Key Air Quality Prediction Model
NOAA’s Air Resources Laboratory (ARL) has delivered significant updates to the Air Quality Model that NOAA’s National Weather Service uses to deliver air quality forecast guidance. NOAA’s partnership with the Environmental Protection Agency (EPA) issues daily air quality forecast guidance as part of a National Air Quality Forecasting Capability. These forecasts include information such as the levels of ozone (O3), smoke, dust and fine particulate matter (PM2.5) in the air we breathe.
As of July 20, 2021 there is an improved time range of air quality forecasts; NOAA’s air quality forecast guidance now extends from 48 hours out to 72 hours. These forecasts offer essential information that limits the public’s exposure to poor air quality and its harmful health effects. Extending the forecast capability to 72 hours assists local forecasters with planning for weekend and multiday event air quality alerts. See full story here.
​
Recently, Dr. Campbell contributed to the latest upgrade of the NAQFC, which is now an integrated, online-coupled air quality model (AQM) part of NOAA's Unified Forecast System (UFS), The initial implementation of this online-coupled system, referred to as AQM version 7 (AQMv7), marked a major milestone in operational air quality forecasting that also further enhanced the predictability of wildfire air quality impacts across the U.S. See Huang et al. (2025) for more details.
RESEARCH SPOTLIGHT
Headlining research published in peer reviewed journals
Dr. Campbell contributes to the World Meteorological Organization (WMO) Air Quality and Climate Bulletin September 2023
"A consensus has emerged that climate-driven increases in the frequency and severity of wildfires can have serious ramifications for enhanced downwind nitrogen emissions and deposition and associated ecosystem impacts like critical load exceedances."
• The 2020 “gigafires” contributed up to 83% of the total nitrogen emissions in the western U.S.
• The 2020 fire emissions led to a 78% increase in annual average nitrogen deposition in California.
• The average nitrogen deposition increases to California’s forests are 6-12 times the critical load.

High Resolution Global Land Surface Datasets using Satellite Measurements for Application to Earth System Models
NOAA technical memorandum OAR ARL, 2024
A global high resolution land surface dataset (GLSD) with universal latitude/longitude grid coordinate is developed at NOAA Air Resources Laboratory (ARL) for the applications to land, weather, and atmospheric composition models. The GLSDs include key land surface properties based on various operational satellite measurements (e.g. MODIS, VIIRS and GEDI), including land surface type, vegetation clumping index, leaf area index, vegetative canopy height, and green vegetation fraction. Critical processing steps are taken to extend the surface properties for a full global coverage, as well as gap-filling within data points that are not available. All
GLSDs are gridded to universal global latitude/longitude gridded coordinates (- 90° – 90° in
latitude and 0° – 360° in longitude) with a consistent spatial resolution of 0.01° (~ 1 km). The
GLSDs are now available at the National Centers for Environmental Information (NCEI) for one year period representative of 2020, and for later years on AWS.
Evaluation of an In-Canopy Wind and Wind Adjustment Factor Model for Wildfire Spread Applications Across Scales
Journal of Advances in Modeling Earth Systems, July 2024
-
This study presents and evaluates a canopy wind model that simulates horizontal wind speeds above and within vegetation canopies
-
Model results agree well with observations and should provide a better representation of wind flow in numerical weather prediction models
-
The wind adjustment factor model provides midflame wind speed estimation, which can be used for the estimation of the rate of fire spread
NOAA’s Global Forecast System Data in the Cloud for Community Air Quality Modeling
Atmosphere, July 2023
​Herein, we present the initial application of the NOAA-EPA Atmosphere-Chemistry Coupler (NACC) in the cloud (“NACC-Cloud”, version 1), which processes NOAA’s operational Global Forecast System version 16 (GFSv16) meteorology on-demand and produces model-ready meteorological files needed to drive U.S. EPA’s Community Multiscale Air Quality (CMAQ) model. NACC is adapted from the U.S. EPA’s Meteorology-Chemistry Interface Processor version 5 (MCIPv5) and is used as the primary model coupler in the current operational NWS/NOAA air quality forecasting model. The development and use of NACC-Cloud in this work are critical to provide the scientific community streamlined access to NOAA’s operational GFSv16 data and user-defined processing and download of model-ready, meteorological input for any regional CMAQ domain worldwide. The NACC-Cloud system was implemented on the Amazon® Web Services High-Performance Computing platform, and results from this work show that the NACC-Cloud system is immediately beneficial to the air quality modeling community worldwide.
DEVELOPMENT AND EVALUATION OF AN ADVANCED NATIONAL AIR QUALITY FORECASTING CAPABILITY USING THE NOAA GLOBAL FORECAST SYSTEM VERSION 16
Geosci. Model Dev., April 2022
NOAA's National Air Quality Forecast Capability (NAQFC) continues to protect Americans from the harmful effects of air pollution, while saving billions of dollars per year. Here we describe and evaluate the development of the most advanced version of the NAQFC to date, which became operational at NOAA on 20 July 2021. The new NAQFC is based on a coupling of NOAA's operational Global Forecast System (GFS) version 16 with the Community Multiscale Air Quality (CMAQ) model version 5.3.1.
