Aura Microwave Limb Sounder (MLS) Derived Meteorological Products (DMPs) Data Usage and Format Description

This document describes the derived meteorological products (DMPs) for the Aura Microwave Limb Sounder [MLS, e.g., Waters et al., 2006; Livesey et al., 2026] Level 2 dataset. The DMPs are meteorological fields interpolated to the measurements’ times and locations, as well as several products derived from those meteorological fields, such as static stability and equivalent latitude (EqL). As described in Manney et al. [2007], interpolation of the meteorological fields is done linearly in time and bilinearly in latitude and longitude. Vertical interpolations are linear in log(θ) for potential vorticity (PV) or in log(pressure) for the other products. EqL is calculated on standard isentropic surfaces (chosen to have resolution comparable to the reanalyses being used) and interpolated linearly in log(θ).

This version of the document was updated for Aura MLS Version 6 data.
