The GPS flight recorder for homing pigeons works : design and first results
No full textThis paper describes a first version of the GPS flight recorder for homing pigeons. The GPS recorder consists of a hybrid GPS board, a patch antenna 19*19 mm, a 3 V Lithium battery as power supply, a DCDC converter, a logging facility and an additional microprocessor. It has a weight of 33g. Prototypes were tested and worked reliably with a sampling rate of 1/sec and with an operation time of about 3 h. In first tests on homing pigeons 9 flight paths were recorded, showing details like loops flown immediately after the release, complete routes over 30 km including detours, rest periods and speed
What causes the irregular cycle of the atmospheric tape recorder signal in HCN?
Full text linkVariations in the mixing ratio of long-lived trace gases entering the stratosphere in the tropics are carried upward with the rising air with the signal being observable throughout the tropical lower stratosphere. This phenomenon, referred to as "atmospheric tape recorder" has previously been observed for water vapor, CO2, and CO which exhibit an annual cycle. Recently, based on Microwave Limb Sounder (MLS) and the Atmospheric Chemistry Experiment Fourier Transform Spectrometer (ACE-FTS) satellite measurements, the tape recorder signal has been observed for hydrogen cyanide (HCN) but with an approximately two-year period. Here we report on a model simulation of the HCN tape recorder for the time period 2002-2008 using the Chemical Lagrangian Model of the Stratosphere (CLaMS). The model can reproduce the observed pattern of the HCN tape recorder signal if time-resolved emissions from fires in Indonesia are used as lower boundary condition. This finding indicates that inter-annual variations in biomass burning in Indonesia, which are strongly influenced by El Nino events, control the HCN tape recorder signal. A longer time series of tropical HCN data will probably exhibit an irregular cycle rather than a regular biannual cycle. Citation: Pommrich, R., R. Muller, J.-U. Grooss, G. Gunther, P. Konopka, M.

Indianapolis Recorder Victory Progress Edition
No full textThe Indianapolis Recorder published the Victory Progress edition on July 7, 1945. Reputed to be the largest issue in the nation ever published by a black newspaper (at that time), it was in celebration of the ending of World War II. It touted a double victory campaign--defeat of the Axis powers abroad and racism at home
