Milestone 2025_01 ISCOD_Dynamics

Local User: P.Condor, I.Manay, C.Portilla

Requester: Goncharenko A 10-day campaign on alert basis is requested, with alert window Dec 15 – Feb 15. The decision to start will be based on predictions of stratospheric conditions. In the case of no anomalous stratospheric conditions (strong polar vortex or sudden stratospheric warming event), the World Day will revert to a 5‐day run at the end of the alert period, 9‐14 February. There should be one week's notice for the alert

Primary Parameters to Measure, including requested time resolution:

Electron density, electron and ion temperatures from lowest possible altitude throughout the F-region. Temporal resolution can be sacrificed and data integration period increased in order to obtain data at lower altitudes.

Secondary Parameters to Measure:

Zonal and meridional components of neutral wind in the lower thermosphere (95-140km), ExB drift, F-region meridional wind.

Requested radars

PFISR, RISR-N, RISR-C, EISCAT (mainland and Svalbard), Millstone Hill, Jicamarca, Kharkiv, QJISR, and PANSY
