Abstract. More than 3 years of airglow observations with a Spectral Airglow Temperature Imager (SATI) installed at the Sierra Nevada Observatory (37.06 • N, 3.38 • W) at 2900 m height have been analyzed. Values of the column emission rate and vertically averaged temperature of the O 2 atmospheric (0-1) band and of the OH Meinel (6-2) band from 1998 to 2002 have been presented. From these observations a clear seasonal variation of both emission rates and rotational temperatures is inferred at this latitude. It is found that the annual variation of the temperatures is larger than the semiannual variation, while for the emission rates the amplitudes are comparable.

“…Since its inception in 1990, BLO has been home from time-to-time for several instruments capable of making mesospheric observations. These have included a very sensitive Fabry-Perot interferometer for OH winds and temperatures from approximately 87 km [20][21][22] , all-sky cameras to observe OH, O 2 , and O( 1 S) emissions 23 , instruments to measure rotational temperatures from OH or O 2 24 , and a digital ionosonde that can also operate in meteor and IDI modes 25,26 . In addition to the USU cluster, radiosondes are launched at 0000 and 1200 UT from five locations within 400 km of ALO: Salt Lake City, UT; Boise, ID; Lander, WY; Grand Junction, CO; and Ely, NV.…”

The Center for Atmospheric and Space Sciences (CASS) at Utah State University (USU) operates the ALO for studying the middle atmosphere from the stratosphere to the lower thermosphere. ALO's mid-latitude location (41.74°N, 111.81°W, 1466 m) is very unique in that it is in the middle of an extensive set of rugged mountains, the Rocky Mountains, which are a major orographic source of gravity waves that may give rise to a longitudinal variation in the mesospheric structure. Mesospheric observations between approximately 45 and 90 km have been carried out on many clear nights with the ALO Rayleighscatter lidar since late 1993. They have been carried out, mostly, with a frequency-doubled Nd:YAG laser producing 18 W at 532 nm and a 44-cm zenith-pointing telescope. To obtain better and more complete observations in the future, a considerably bigger steerable telescope, an alexandrite ring laser for resonance scatter, and an expanded data-acquisition system are being developed. The observations in the extensive existing database have been reduced to provide absolute temperature profiles, which provide important information for understanding the physics and chemistry of the middle atmosphere and for examining global change. They have been used to make a mesospheric temperature climatology that has been and is being used to examine secular, annual, seasonal, and tidal variations, to compare with other temperature observations and with modeled temperatures, and to study mesospheric inversion layers. Day-to-day changes in the temperature profiles are also being compared to meteorological parameters to see if mesospheric changes can be related to low-altitude sources. Temporal and spatial fluctuations in the density profiles have also been examined to provide more direct information on gravity wave activity. And, on 24 June 1999 UT, the lidar probed the first known noctilucent cloud to penetrate to this low latitude, approximately 10° equatorward of previously reported sightings and detections.
