AEROMMA Planning

Schedules

NASA DC-8

April – August 2023 Calendar

AEROMMA has 200 flight hours for approximately 22 science flights, including test and transit flights, and consists of both a West and East coast deployment. West coast operations will be focused on the Los Angeles basin and the coastal Pacific marine environment. East coast operations will characterize emissions from a number of US megacities and may conduct marine survey flights in the North Atlantic.

We anticipate conducting 2-3 flights for the major megacity targets covering weekday/weekend, urban/rural gradients, and diurnal cycles. Depending on meteorological conditions each flight to a megacity can cover other smaller cities or more than one megacity. Two flights in Los Angeles and the Central Valley were already conducted during FIREX-AQ in 2019.

We estimate 8-10 flights dedicated to the survey of the marine atmosphere. The east and west coast regions of the US have variable NOx mixing ratios, temperature, background aerosol, and cloud properties that are accessible throughout the flight range of the NASA DC-8. This variability provides the necessary statistics for studying the impact of these parameters on the distribution and fate of marine emissions, oxidation chemistry and aerosol abundance and composition.

NOAA Twin Otter

June – August 2023 Calendar

CUPiDS has 110 science flight hours distributed occurring on 18 flight days over a time period of five and one half weeks. This assumes a typical flight duration of 4 hours and roughly 20 hours of flight each week: two 4 hour flights back-to-back with a refueling stop and one single flight each week. The science flight schedule accommodates necessary aircraft maintenance (EMMA) in July.
