TitleInfluence functions for the INFLUX Tower Network
Date2024
AbstractThis data consists of influence functions created for the INFLUX tower network for the purpose of calculating methane and carbon dioxide enhancements in the region. Footprints were generated using the Lagrangian Particle Dispersion model (LPDM, Uliasz 1993) was run from March 2020-May 2023. The model uses in-house WRF simulations for the meteorological transport as described in Davis et al., (2017). Twenty four hundred (2400) particles were released during each hourly period and are traced back 72 hours backwards in time. A static binning height of 110 m AGL was used to calculate surface influence. This directory will later be updated with influence functions generated using HYSPLIT-STILT. Lat/Lon grid information for the LPDM influence functions are contained within the influence functions themselves. Tower coordinates and heights can be found in tower-locations.csv
