Historic Palmer Drought Severity Index data sets and plots for Georgia Division 9 have been updated in the GCE Data Portal to cover the period of January 1895 to February 2021. These indices are useful for characterizing the timing and severity of drought events in the long-term climate record. The data were downloaded from NOAA and converted into tabular data sets with decoded state and date columns to simplify filtering, plotting and analysis. More information about these indices and data sets is available here. 03/02/2021 – Data Release

The GCE Data Toolbox for MATLAB is a software framework for metadata-based processing, quality control and analysis of environmental data. The software was originally developed by Wade Sheldon for GCE data management in 2001 and has been continually maintained and refined. This software was released under an open source license in 2010 and is currently in use at many other LTER sites and institutions for sensor data processing.

Please be aware that the rain gauge installed on the Marsh Landing weather station at the Sapelo ferry dock stopped recording precipitation some time in October 2020. The gauge is being removed by SINERR personnel for recalibration and will be replaced soon. Affected data sets in the GCE Data Portal have been flagged to reflect the instrumentation problem. If your analysis requires precipitation, note that 15 minute precipitation data are available from the GCE Flux Tower a few kilometers up the Duplin River from Marsh Landing, as well as on the mainland at Hudson Creek/Meridian.

The anemometer at the Hudson Creek/Meridian weather station was replaced following damage from Hurricane Matthew in October 2016. However, wind speeds reported by the new anemometer have always been significantly lower than those reported by the prior instrument and parallel measurements at the Marsh Landing weather station on Sapelo Island and Gray's Reef buoy. After numerous checks and recalibrations, and installation of a second anemometer for comparison, USGS has finally found and corrected the issue. In brief, the sensor was internally configured to report in meters per second instead of the USGS standard mph, leading to a 2.4-fold error in magnitude.
