A suite of environmental parameters in the Burrishoole catchment, the freshwater Lough Feeagh and estuarine Lough Furnace are routinely measured as part of the ongoing LTER (long-term ecological research) program of monitoring. Parameters include meteorological variables measured at multiple spatial locations and hydrographic variables on each lough system. The timeframe of each data series vary depending on the instrument type and sampling location. These datasets includes various data streams from different sources compiled for a specific timeframe of interest, an extreme storm event in December 2015.
