=== CEDAR Support of the TIMED Initiative ===

Under an agreement with APL, the CEDAR Database (DB) at HAO/NCAR is responsible as one of the sites for data from the Ground-Based Investigators (GBI) of the TIMED program who have instrumental or model data. The data from the [[Timted:Ground Based Instruments|Ground Based Instruments]] can be obtained through the [[Data Services:Main|Data Services]].

=== Links to plots and data at GBI data sites ===

Some GBI instruments show plots of their data, and in some cases links to get the data. Often, these are automated sites so the data include all data, including optical night-time data during cloudy periods or whatever. In some cases, only the good data are passed onto the CEDAR DB.

=== GBI-TIMED Calibrations/Collaborations ===

There are 4 instruments on the TIMED satellite: GUVI, SABER, SEE, and TIDI. SEE is the only instrument which does not measure the same thing as GBIs. Of the other three, this is an estimate about possible calibrations, validations or collaborations.

# GUVI - Ne from ISRs, auroral [O] variations from 4 Channel Photometers, Tn &gt; 100 km from red line FPSs (Poker Flat), auroral species ratios from CCDSs.
# SABER - [/timed/saberobs.pdf SABER Observations] (pdf file) and [/timed/sabervalid.pdf SABER Validation Products] (pdf file).
#* Ti (or Tn) from ISRs day and night &gt;~90km
#* Tn at night from near OH peak ~87 km from MIs, CCDSs, FPSs (using OH filter) -- all every several min, and narrowband temperature lidars using OH filter over the night
#* Tn at night from near O2 peak ~93 km from MIs, FPSs and narrowband temperature lidars (using O2 filters)
#* Tn at night from near OI 557.7 nm peak ~97 km from FPSs (using OI 557.7 nm filter)
#* Tn profile at night (mostly) from sodium lidars from ~75-110 km, ~1 hr, ~1 km
#* Tn profile at night (mostly) from ozone lidars from ~15-50 km (see also [http://www.ndsc.ws http://www.ndsc.ws])
#* Tn profile at night (mostly) from Rayleigh lidars from ~45-85 km, ~1 hr, ~0.1 km
#* neutral density profile at night from Rayleigh lidars from ~45-95 km, ~1 hr, ~0.1 km, with fixed density (like MSIS) at some altitude (like 50 km)
#* [O3] from ~15-50 km from ozone lidars (see also http://www.ndsc.ws)
#* [O] ~100-150 km compared to MSIS profile from 4-channel photometers at night during aurora
#* [NO] from ~90-130 km from ground microwave at Kitt Peak
#* [H2O], [O3], [O2] from ~50-70 km from ground microwave at Kitt Peak
# TIDI - winds between 70-100 km from MLT radars, lidars, ISRs, and FPSs; Tn from lidars, ISRs, FPIs, MIs, CCDSs, and narrowband temperature imagers; gravity waves from imagers; some intercomparison of radiances with ground stations.
