readme.sodar Readme file for MIPS Sodar data (S.Paech) The relevant sodar wind files are those of the format ECHYMMDD.CDF where: ECH -> file name prefix Y -> single digit year MM -> month DD -> day These files are in ascii format and are self-explanatory. The data were averaged over 15 minute periods with the ending time indicated. If you are interested in data from each ping (moments files), refer to the .MOM files. This data has not been screened or quality controlled. The directional Sodar data has NOT been adjusted to take into account the MIPS orientation during each deployment. Furthermore (unfortunately) the Sodar antenna azimuth setting (the direction the Sodar thinks the MIPS was pointing in) was changed multiple times during the project. To correct for this, refer to the file sodar_correction.dat. For each deployment, the difference between the MIPS heading and Sodar antenna azimuth needs to be added to the Sodar wind directions to get the true directions. For example, if the MIPS heading was 180 deg and the Sodar antenna azimuth setting was 200 deg, -20 deg needs to be added to the Sodar wind direction data. In a couple of instances, the Sodar antenna azimuth setting was changed DURING a deployment, making the above issue even more convoluted. These instances are noted in sodar_correction.dat. We apologize for this inconvenience. Refer to bamexlog.dat for information regarding MIPS setup during each deployment.
