AARDDVARK operation

AARDDVARK modellingMain focus is modelling of AARDDVARK data, working alongside interpretation with BAS.

AARDDVARK VLF → Electron Precipitation Fluxes

In our modelling focus we have made extensive use of DEMETER data (for which Rodger is a guest investigator) and also POES particle data. We have developed in house knowledge and tools to work with both datasets.

WWLLN Host

We run one of the two WWLLN central processing computers, operate three WWLLN receivers, and sit on the WWLLN Management Committee. The WWLLN PI is of course Bob Holzworth (Univ. Washington).
