RENOIR in Brazil
Location: -7.39 N, -36.53 E; mag: -6.81 N
Instruments: MiniME FPI (630.0 nm), 2 single-frequency GPS scintillation monitors (spaced by 44.5 m).
Other notes: INPE and UFCG operate a photometer, allsky imaging system, dual-frequency GPS receiver (soon), digisonde, and meteor radar at this site.
Cajazeiras, PB
Location: -6.89 N, -38.56 E; mag: -5.75 N
Instruments: MiniME FPI (630.0 nm), 1 single-frequency GPS scintillation monitor and 1 dual-frequency TEC/Scintillation monitor (separated by 30.6 m), PICASSO wide-angle imaging system (630.0-nm, 777.4-nm, and background filters).
Instrument notes:
PICASSO
- Typical integration times are 90 s per filter. Due to low electron densities, we expect to concentrate our observations on the 630.0-nm filter which will still give high signal-to-noise. Most likely filtering scheme will be 630.0, 630.0, background, 630.0, 630.0, 777.4.
- This system operates when the sun is 18 degrees below the horizon and the moon is 0 degrees below the horizon.
MiniME
- The integration time to be used is still an unknown. Based on observations in Urbana from 2007-2008, we expect to be able to use < 5-min integration times. This will be decided upon after initial data are obtained when the PCI cards have been repaired.
- The common volume (CV) look directions have been calculated based upon an assume emission layer altitude of 250 km. For the orthogonal look directions (to both the north and south; labeled as 'O' in the map image), the elevation angle from each site is 57 deg. For the in-line common volume (labeled as 'X' in the map image, the elevation angle from each site is 65 deg.
- Several observation modes are possible, including (feel free to suggest others):
- Maximum temporal resolution: Point both FPIs to either the north or south orthogonal CV and rapidly take data. A vertical measurement would be taken every 30 min for calibration purposes.
- Wave propagation mode: Cycle each FPI through observing the north CV, in-line CV, and south CV. A vertical measurement would be taken after a certain number of cycles (depending on integration times) for calibration purposes.
- Do we need a tidal mode in which we also make observations in the look directions far away from the CV to get a spatial distribution of the measurements?
Instrument status:
All of the equipment is currently on site. The optical instrumentation is not working, due to PCI video cards that need to be repaired. We expect to have the PCI cards replaced in July.
Univ of Illinois Equipment in Peru
- U of Illinois will install an all sky imager in the same location as John Meriwether's FPI near Jicamarca. It will measure OH airglow and provide wave information at about 87 km.
Andes Lidar Observatory in Chile
- The U of I Na lidar, an all sky imager for OH and meteor radar will be deployed at Cerro Pachon in September this year.
- Utah State Univ (Mike Taylor) will install a Mesospheric Temperature Mapper.
- Aerospace Corp (Jim Hecht) will install an airglow imager
