TAMDAR AERI-bago Validation Experiment (TAVE) Daily Summary ----------------------- Date: 26 February 2005 CST (Saturday) 0000-2400 UTC Location: Memphis Air National Guard at MEM Airport Operators: K. Bedka and T. Wagner http://cimss.ssec.wisc.edu/tamdar/ Weather Conditions: High in the low to mid 60's, mid and upperlevel altocumulus and cirrus, light winds, beautiful day. Rain expected tomorrow Instrument Status: * Surface sensors (temperature, relative humidity, pressure and winds) working and archiving * Ceilometer working and archiving data * AERI working and archiving data * Radiosonde launches went perfectly 0100 Radiosonde Launch - Great sonde launch and data set 1430 Radiosonde Launch - Great sonde launch and data set 1615 Radiosonde Launch - Great sonde launch and data set 2015 Radiosonde Launch - Great sonde launch and data set, sonde inadvertently launched at 2000 UTC...operators thought sonde was scheduled to launch at 2000 UTC, tower was called 10 and 2 mins prior according to launch procedures 2300 Radiosonde Launch - Great sonde launch and data set * GPS system is collecting data and archiving. Data downloaded successfully from GPS unit to external laptop computer The operators would like to thank base security for friendly conversation and interaction that livened up our day. In addition, we would like to thank them for a tour around the periphery of a C-5 Galaxy cargo plane. Science: Comparisons between MEM TAMDAR and RUC20 data revealed that RUC20 did not capture the strong surface heating that occurred during the day. RUC20 was at least 5 K coller than the lowest level of TAMDAR profiles. In addition, TAMDAR better captured moisture advection above the 800 mb level that began during the early afternoon. Comparisons will be attached with tomorrow's report detailing the comparison of these 2 datasets. Miscellaneous: Erik Olson left MEM today AERIBago contact number: 608-219-0565 Cheers, Kris Bedka
