1. A method comprising:
attaching, to a drill string disposed at least partially within a wellbore and supported by a surface rig system, a sensor calibration clamp tool, the sensor calibration clamp tool positioned on the drill string at a surface location proximate to the surface rig system, wherein the sensor calibration tool comprises a sensor bank comprising a plurality of tool sensors, each of the plurality of tool sensors configured to measure a respective operational parameter of a plurality of operational parameters;
conducting sensor calibration while the sensor calibration clamp tool is attached to the drill string at the surface location, wherein the sensor calibration comprises:
receiving, from a first tool sensor of the plurality of tool sensors, a first tool sensor measurement of a first operational parameter of the plurality of operational parameters;
receiving, from a first rig sensor positioned on a first surface component of the surface rig system, a first rig sensor measurement of the first operational parameter; and
calibrating the first rig sensor based on a comparison of the first tool sensor measurement with the first rig sensor measurement; and
while the drill string is lowered downhole, continuing to position the sensor calibration clamp tool on the drill string at the surface location by detaching and re-attaching the sensor calibration clamp tool to the drill string.
