POAM III - Version 4 DATA DESCRIPTION Introduction This readme file contains information about the data provided by the Polar Ozone and Aerosol Measurement (POAM) III instrument developed by the Naval Research Laboratory. It includes implementation of the sample READ software. This data set is available through the Langley Atmospheric Science Data Center as: POAM3 Each data granule contains one month of data for a particular hemisphere, taken at approximately 101 minute intervals. The latitudinal extent of data for the northern hemisphere is 54.68 to 71.01 and -62.55 to -88.11 for the southern hemisphere. The longitude ranges from 0 to 360. The data consists of profiles of ozone, nitrogen dioxide (NO2), and water vapor concentration, and aerosol extinction at 442 nm and 1018 nm.

POAM III measures solar extinction in nine narrow band channels, covering the spectral range from 354 to 1018 nm. Solar extinction by the atmosphere is measured using the solar occultation technique; the sun is observed through the Earth's atmosphere as it rises and sets, as viewed from the satellite. POAM III was launched aboard the French SPOT-4 satellite in March 1998 into a Sun synchronous polar orbit. As seen from the satellite, the Sun rises in the north polar region and sets in the south polar region 14.2 times per day. Sunrise measurements are made in a latitude band from 55-71 degrees north while sunsets occur between 63-88 degrees south. Further details about the POAM III instrument can found in Lucke, et al., J. Geosphys. Res, 104, 18, 785-18, 799, 1999. 2.1 Data Quality The data quality information is available from the "Status of POAM III Version 4 retrievals" and "Description of POAM III Version 4 Retrieval" documents. http://eosweb.larc.nasa.gov/PRODOCS/poam3/table_poam3.html/poam3_ver4_retrievals_status.pdf http://eosweb.larc.nasa.gov/PRODOCS/poam3/table_poam3.html/poam3_ver4_documentation.pdf Other relevant publications contain more detail and are listed below in Section 7.0. 2.2 Science Point of Contact Dr. Karl Hoppel Remote Sensing Physics Branch, Code 7227 Naval Research Lab Washington, DC 20375-5320 USA E-mail: karl.hoppel@nrl.navl.mil Phone: (202) 767-1320 Fax: (202) 767-0005 3.0 Data Format The POAM III data is provided in HDF file format. Further information regarding HDF file format and free HDF software is available at the NCSA anonymous ftp server ftp.ncsa.uiuc.edu, or at the web site http://hdf.ncsa.uiuc.edu 3.1 Data File Naming Convention Northern hemisphere and southern hemisphere measurements are in separate files. The POAM III data granules are prefixed with "poam3_ver4_" to indicate they belong to this data set. The next two characters indicate the hemisphere (nh -northern, sh - southern), followed by the year and month and the hdf extension. Example filename: poam3_ver4_nh_199808.hdf POAM III northern hemisphere data for August 1998 4.0 Science Parameters Information Each POAM III measurement is uniquely identified by the orbit (REV) number and hemisphere. All orbital sunset measurements are in the southern hemisphere while sunrises are in the northern hemisphere. Because separate HDF files are made for the south and north, the REV number serves as a unique identifier within each file. The parameters in the HDF files are listed below. The array dimension "n" identifies the orbit. Missing values are indicated by the fill value of -99 in all arrays. The lowest altitude for valid retrieval data is determined by lowest altitude to which the POAM III instrument was able to track the sun. The geophysical parameters of temperature, pressure, and potential vorticity were obtained from the UK Meteorological Office (UKMO) data by interpolating these fields to the time and location of the POAM III measurements. These parameters are provided as ancillary data that are useful for the process of analyzing the POAM III measurements.

The IDL VM utility is "read_poam3v4_hdf.sav". If you have purchased IDL, the program, "read_poam3v4.pro", that this .sav file was creted from is also available. Please refer any questions regarding this utility or the program to the Langley ASDC User and Data Services Office. The read_p3ver4_hdf.sav runs using IDL VM. The IDL VM is a free runtime version of IDL available from ITT Visual Information Solutions at http://www.ittvis.com/Downloads/ProductDownloads.aspx. This utility has been tested with IDL 6.2 Virtual Machine. As written, the utility reads the selected parameter(s) and writes to an output file the data values for each measurement. The output filename is generated by using the input filename and replacing the '.hdf' extension with '.out'. A dialog box displays the begin and end dates of the input file and a list of parameters to select. Modify the Begin Dateand End Date fields to specify a subset of the monthly file. The parameters available for selection are: - UKMO Pressure - UKMO Temperature - UKMO Potential Vorticity - Ozone (O3) Concentration - Water Vapor (H2O) Concentration - Nitrogen Dioxide (NO2)Concentration - Aerosol Extinction The data values for the selected dates and parameters are written to the output file. Note: n = total number of measurements The following parameters are included in all output files: Date (YYYYMMDD)[1: n] Orbit Number (unique id) [1: n] Seconds of day (UT) [1: n] Latitude (deg) [1: n] Longitude (deg) [1: n] Maximum sunspot index for profile [1: n] Ancillary data parameters: Selecting "UKMO Pressure" outputs the following parameter: UKMO Pressure (mb) at altitude km [1: n, altitude level] Selecting "UKMO Temperature" outputs the following parameter: UKMO Temperature (K) at altitude km [1: n, altitude level] Selecting "UKMO Potential Vorticity" outputs the following parameter: UKMO Potential Vorticity (K/s/Pa, PV units) at altitude km [1: n, altitude level] The ancillary data altitude parameter is included once with any of the parameters listed above: Anc. data altitude grid 0-60 (km) [1: n] Science parameters: Selecting "Ozone (O3) Concentration" outputs the following parameters: Ozone Concentration (molecule/cc) at altitude km [1: n, altitude level] Ozone Concentration Error Bars (molecule/cc) at altitude km [1: n, altitude level] Ozone Quality Flag at altitude km [1: n, altitude level] Ozone altitude grid 5-60 (km) [1: n] Selecting "Water Vapor (H2O) Concentration" outputs the following parameters: H2O Vapor Concentration (molecule/cc) at altitude km [1: n, altitude level] H2O Vapor Concentration Error Bars (molecule/cc) at altitude km [1: n, altitude level] H20 Vapor Quality Flag at altitude km [1: n, altitude level] H2O Vapor altitude grid 5-50 (km) [1: n] Selecting "Nitrogen Dioxide (NO2) Concentration" outputs the following parameters: NO2 Concentration (molecule/cc) at altitude km [1: n, altitude level] NO2 Concentration Error Bars (molecule/cc) at altitude km [1: n, altitude level] NO2 Quality Flag at altitude km [1: n, altitude level] NO2 altitude grid 20-45 (km) [1: n] Selecting "Aerosol Extinction" outputs the following parameters: Aerosol wavelengths (micron) [1: n] Aerosol Extinction (km-1) at wavelength microns at altitude km [1: n, wavelength, altitude level] Aerosol Extinction Error Bar (km-1) at wavelength microns at altitude km [1: n, wavelength, altitude level] Aerosol altitude grid 5-25 (km) [1: n] 6.0 Implementing Utility and Sample Output The utility can be used to output all parameters for the entire month, a subset of the parameters, a subset of the month,or a subset of the month and parameters. 6.1 Running IDL VM Utility Download the IDL VM from http://www.ittvis.com/Downloads/ProductDownloads.aspx and install. Start IDL VM. Select the read_p3ver4_hdf.sav file. Choose the hdf file of interest. The utility assumes that the hdf files are on the same system as IDL VM. Write permission is needed for the directory where the data are located. A dialog box displays the begin date, end date, and parameters. At completion, an output file will contain data values of the selected parameter(s). The output filename is generated by using the input filename and replacing the '.hdf' extension with '.out'.
