1. An apparatus comprising at least one processor, and at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus at least to:
collect training data comprising radio measurement information and one or more performance metrics associated with a plurality of cells,
wherein the radio measurement information comprises at least a set of received interference power values for each cell of the plurality of cells over a time window, and a set of signal-to-interference-plus-noise ratio levels for each cell of the plurality of cells over the time window;
determine an operational received interference power value per a cell of the plurality of cells by determining a measure of central tendency of the set of received interference power values of the cell;
determine a deviation value of the cell from the operational received interference power value, based on one or more new received interference power values of the cell that are measured after collecting the training data;
determine, based at least on the set of signal-to-interference-plus-noise ratio levels and the one or more performance metrics of the cell comprised in the training data, a vulnerability threshold above which a performance of the cell is impacted by remote interference caused by tropospheric ducting;
compare the deviation value of the cell to the vulnerability threshold; and
determine, based at least on the comparison, whether the performance of the cell is impacted by the remote interference caused by the tropospheric ducting.
