1. A computer comprising a processor and a memory storing instructions executable by the processor to:
receive optical data from an optical sensor of a vehicle;
adjust the optical data using an adjustment model;
measure a first value from the optical data over a duration, the first value being time-varying and aggregated from the optical data per time step;
predict a second value from the optical data over the duration based on the first value, the second value being time-varying and aggregated from the optical data per time step;
measure the second value from the optical data over the duration;
receive motion data from a motion sensor of the vehicle over the duration;
determine a type of event affecting the optical sensor based on the motion data, the predicted second value, and the measured second value; and
modify the adjustment model using the predicted second value and the measured second value;
wherein adjusting the optical data using the adjustment model is based on the motion data;
modifying the adjustment model is based on the motion data;
modifying the adjustment model is based on the type of the event; and
the type of the event is based on a correlation between the motion data and a mathematical function of the measured second value.
