An earlier brief report on the status of the Poker Flat, Alaska, MST radar
appeared last year in MAP Handbook 14. The purpose of the present note is to
bring that report up to date.
The Poker Flat MST radar ceased normal operations in Apr_ 1985, following
more than six years of almost continuous data taking. Analyses of these data
have already yielded over ninety research papers, five Ph.D and two MSc.
dissertations.
The radar is now being configured to measure gravity-wave momentum flux in
the troposphere, lower stratosphere, upper mesosphere, and lower thermosphere.
The major change to the system involves modifying the antenna array to enable
both (orthogonal) oblique beams to be automatically steered. GWMF data will be
obtained on pairs of vertically symmetric beams in the manner described by
VINCENT and REID (1983). Current funding is sufficient to complete this
modification and to operate in this new mode until Fall 1986.
An additional effort is underway to prepare an archive of the existing
six-year Poker Flat data set. This archive, when complete, will be transferred
to the National Center for Atmospheric Research (NCAR) for use by anyone in the
scientific community.
