TAMDAR AERI-bago Validation Experiment (TAVE) Daily Summary ----------------------- Date: 04 March 2005 CST (Sunday) 0000-2400 UTC Location: Tennessee Air National Guard at MEM Airport Operators: K. Bedka, S. Bedka, S. Cultice http://cimss.ssec.wisc.edu/tamdar/ Weather Conditions: Mostly sunny skies all day. A few altocumulus in the morning. Highs in the mid-upper 60s. Strong southerly winds gusting to 24 kts in the afternoon. Instrument Status: * Surface pressure, RH, and tmeperature sensors working and archiving. Anemometer is still malfunctioning. Please note, the wind data contained in the surface data files are invalid. * Ceilometer working and archiving. * GPS system working and archiving * AERI working and archiving. * Radiosonde system is working and archiving. 0100 Launch normal, data good. 1430 Launch normal, data good. 1615 Launch normal, data good. 2015 Launch normal, data good. 2300 Launch was successful, but there was an error in data aquisition for this launch. Legitimate data stream ended after 93 seconds. The operators noticed that the temperature did not adjust to the outdoor ambient temperature (the minimum temperature on the sounding was too warm to be outside the Bago). Therefore, the conclusion was that the battery failed before the launch. Science/Miscellaneous: AERI realtime cross sections are now being posted on the CIMSS TAMDAR website (see link above). General trends in temperature were similar between the AERI, the operational RUC20 model,and TAMDAR. Some variations were visible in the relative humidity and dew point profiles. Some vertical striping was visible in the AERI profiles, which may be a function of the high temporal sampling rate of the AERI. However, some additional quality control may be needed for the AERI data. The operators have 9 sondes remaining within the AERIbago.
