Abstract:
Near-simultaneous all-sky (160 degrees field of view) observations of the OI 630.0 nm, OI777.4 nm, OI557.7 nm and 589 nm nightglow emissions are being carried out on a routine basis at ZF-2 Cuireiras Biological Reserve (2.59 degrees S, 60.22 degrees W, altitude 87 m), Amazonas state, Brazil, since July 2015. In the thermosphere-ionosphere, three types of phenomena are studied using 630.0 nm and 777.4 nm observations: (1) brightness waves (BW) associated with the midnight temperature maximum (MTM), (2) electron density enhancement associated with plasma blobs and MSTID with characteristics matching a Perkins-instability. In the mesosphere we study gravity waves events, probably generated by lower atmospheric due to treetops of the Amazon rainforest.
