foqat (version 2.0.8.2)

Field Observation Quick Analysis Toolkit

Description

Tools for quickly processing and analyzing field observation data and air quality data. This tools contain functions that facilitate analysis in atmospheric chemistry (especially in ozone pollution). Some functions of time series are also applicable to other fields. For detail please view homepage. Scientific Reference: 1. The Hydroxyl Radical (OH) Reactivity: Roger Atkinson and Janet Arey (2003) . 2. Ozone Formation Potential (OFP): , Zhang et al.(2021) . 3. Aerosol Formation Potential (AFP): Wenjing Wu et al. (2016) . 4. TUV model: .
