These IDL, FORTRAN 90, Python, C++ and Matlab routines are available to aid in reading the RSS bytemap daily and time-averaged data files. The read routines have been tested and work correctly within our PC Windows environment. We do not guarantee that they work perfectly in a different environment with different compilers. If portability is a problem, we suggest using the Python code. We provide data from the AMSR-2 instrument on GCOM-W1, the AMSR instrument on Aqua (AMSR-E) and the AMSR instrument on ADEOS-II (which we refer to as AMSR-J). These instruments, though similar, have different swath widths. We process the data using v5 (AMSR-J) and V7.1 (AMSR-E) and V7.2 (AMSR-2) algorithms into ocean products of sea surface temperature, ocean surface winds (10 meters height), atmospheric water vapor, cloud liquid water, and rain rate. The FORTRAN subroutines are located in read_amsr_subroutines_v7.f read_amsr_day returns a 1440x720x7x2 real array called amsr_data. A description of the data within this array is at the top of the subroutine. read_amsr_averaged returns a 1440x720x6 real array called amsr_data. The 3-day, weekly and monthly binary files can all be read with this one routine. Just supply the correct filename with path. These routines have been tested with Intel Visual Fortran 90. Data files must be unzipped prior to using these routines. Use a file unzipper of your choice. The IDL read_amsr_day_v7.pro routine requires a full path filename and returns seven 1440x720x2 real arrays. The time-averaged data files are read using read_amsr_averaged_v7.pro. This routine returns six 1440x720 real arrays. A description is provided within the routine. These routines have been tested with IDL 8.4 Data files do not need to be unzipped when using the /compress keyword in the read call. Matlab read routines, read_amsr_day_v7.m and read_amsr_averaged_v7.m, function similar to the IDL routines listed above and have been tested with Matlab 7.1 Data files must be unzipped before using the matlab routines. The Python code consists of amsr_daily_v7.py and amsr_averaged_v7.py. Both require the use of bytemaps.py. The example_usage.py code provides a main program that you can use to test the data or adapt to your needs. Description of file contents is provided at the top of each routine. C++ read routines consist of amsr2_daily.h, amsr2_daily.cpp and amsr2_example.usage.cpp as well as averaged files for each. Files are separated into AMSRE and AMSR2, but either will work on the other. The amsr2_example.usage.cpp and amsre_example.usage.cpp both provide a main program that can be used to test the data or use as a starting point to adapt to your needs. A description of the file contents is provided at the top of each routine. dataset.h and dataset.cpp are required for programs to work. Once you have further developed one of these skeleton programs to suit your processing needs, you may wish to use the verify file to confirm that the data files are still being read correctly. Please check that you have the correct verify file. If you have any questions regarding these programs, or the RSS binary data files, contact our support desk at at support@remss.com
