CEDAR Frontiers: Tidal variability and wave interactions in the MLT region Chiao-Yao (Joe) She Colorado State University Joeshe@lamar.colostate.edu Richard L. Collins University of Alaska Fairbanks In one sentence: It is very much there, yet scientists can’t predict it, nor do they know how to interpret it. 24 h lidar measurements of Na density, temperature (top) and potential temperature (bottom) at ort Collin.

Tidal-GW interactions Planetary-GW interactions Nine-day continuous observation Tidal perturbations & variability She et al., GRL, 2004

Some Facts and Questions Why do tidal models predict semidiurnal tidal amplitudes much smaller than observed amplitudes? Possible causes: (1) lower atmospheric sources are not resolved correctly, (2) vertical resolution needs to be higher (3) influence of tide-GW interaction unclear. In view of observed midnight diurnal local heating, to what extent does the phase of temperature tide can be uncorrelated with the phase of horizontal wind tide? More difficult to handle tidal variability : need to know (1) GW sources (time and space), (2) the presence of PWs and their modes, (3) the prescription of tide, GW and PW interactions.

Truely Coordinated Campaigns PSMOS June-August 1999 Campaign (Pancheva et al., JASTP, 2002) – somewhat coordinated First CAWSES Tidal Campaign, Sep 01 – Oct 31, 2005 (Leader: W. Ward) – somewhat coordinated Coordinated campaigns with well-distributed Radars (Meteor, MF and ISR), Lidars (Metals with TUV_24-hr capability, Rayleigh) and Satellite diagnostics will fully characterize large-scale waves and advance our understanding of tidal variability and wave interactions.

Proposed Class I Instruments and Coordinated Campaigns Beef up all 3 sodium lidars in the CRRL to 24-hour capability and large telescope Mobile lidars in concert with AMISR More stations (both radar and lidar) to cover minimal longitudes and latitudes as required by modelers Community designed (led by modelers and wave specialists, reality-checked by instrument “owners”) coordinated campaigns.
