As noted in the daily summary, the windcube lidar has had a database issue the last couple of days. The lidar had been saving spectral data which might be useful if we ever need to reprocess the data (some papers show how reprocessing the spectra can result in extending the range of the lidar by extracting moments out of noisy spectra in a similar manner to how NIMA extends the range of the radar wind profilers). This results in much more data than normal operation, which shouldn't be a problem as long as the extra data can be cleared off the database. Unfortunately there appears to be a problem with the clearing off process not freeing up disk space after the data has been deleted. We turned off the spectral collection last week and have been deleting data but the database system hasn't freed up disk space, and the lidar stopped collecting data.
