Summary
Abstract:
DATA ACCESS The Electra data are available upon request from the National Center for Atmospheric Research (NCAR) in Boulder, CO ( http://dss.ucar.edu/pub/toga_coare/) and from the National Climatic Data Center (NCDC) in Asheville, NC ( http://lwf.ncdc.noaa.gov/oa/coare/). BACKGROUND-TOGA COARE TOGA COARE was a multidisciplinary, international ... research effort that investigated the scientific phenomena associated with the interaction between the atmosphere and the ocean in the warm pool region of the western Pacific. The field experiment phase of the program took place from 1 November 1992 through 28 February 1993 and involved the deployment of oceanographic ships and buoys, several ship and land-based Doppler radars, multiple low and high-level aircraft equipped with Doppler radar and other airborne sensors, as well as a variety of surface based instruments for in situ observations. During the four-month field phase of TOGA COARE, the NCAR Electra operated out of Honiara in the Solomon Islands from 16 November 1992 to 18 February 1993, conducting 32 flights for a total of 204 hours. DATA AVAILABILITY 1) Data from NCAR/RAF The processed Electra in-situ data are available on two Exabyte tapes that were produced with GENPRO-II data processing software. The data come with an extensive hardcopy report that includes the following: output tape log, research flight and data quality reports, summary of IRU performance and in-flight calibration maneuver, documentation describing characteristics of each measurement and algorithms used in data processing, publications on airborne humidity, air motion and radiation measurements, cloud physics instrumentation, a summary of project calibrations, a list of parameters provided by the final data processing, output tape format description, GENPRO tape read instructions, video field logs and project slides. For more information, contact Ron Ruth (ruth@ncar.ucar.edu) at NCAR. 2) Data from Scripps Institute of Oceanography The following ten-km-averaged data from all 24 low-level Electra flights (altitude less than 60 m), prepared by the Marine Meteorology Research Group at Scripps Institute of Oceanography, are available: N308D_atm.asc jday spm ta thetae sh tsurf ws irb irt swb swt N308D_bulk.asc jday spm Qe Qh Tau Zl ta10 ws10 sh10 N308D_eddy.asc jday_eddy spm_eddy wq wpt wur wvr N308D_pos.asc jday spm latg longg alt ps Variable Units Comments ------- ----- -------- jday Julian Day jday_eddy Julian Day -time that matches eddy fluxes only spm seconds past midnight -midnight is on the day prior to the day of the flight, GMT (i.e. spm = 86500 for a nov15 flight; date is actually 100 seconds into nov 16 GMT) spm_eddy sec past midnight -same as above only for eddy flux variables ta deg C -ambient temperature, fuselage ta10 dec C -temperature corrected to 10 m using the COARE bulk v2f code thetae dec K -equivalent potential temperature sh g/kg -specific humidity sh10 g/kg -humidity corrected to 10 m using the COARE bulk v2f code tsurf deg C -radiometric sea surface temperature, JPL ws m/s -GPS corrected wind speed ws10 m/s -wind speed corrected to 10 m using the COARE bulk v2f code irb,irt W/m2 -infrared irradiance, bottom, top swb,swt W/m2 -shortwave irradiance, bottom, top ps mb -static pressure, fuselage Qe W/m2 -COARE bulk v2f latent heat flux Qh W/m2 -COARE bulk v2f sensible heat flux Tau m2/s2 -COARE bulk v2f wind stress Zl - -COARE bulk v2f stability parameter (Z/L) wq W/m2 -eddy correlation latent heat flux wpt W/m2 -eddy correlation sensible heat flux wur m2/s2 -eddy correlation along wind momentum flux wvr m2/s2 -eddy correlation cross wind momentum flux Questions should be directed to Yolande Serra (yserra@ucsd.edu).
