Surface analysis MSLPMSLP Mean sea level pressure is the pressure at sea level, or, when measured at a given elevation on land, the station pressure reduced to sea level assuming an isothermal layer at the station temperature. falling 10.4 hPahPa A Hectopascal is the SI unit of pressure and identical to the Millibar in the last 3 hrs at Belmullet (1), with dewpoints of 11°C coming into Valentia (2).
