what's the meaning of standard sea-level pressure and standard sea-level temperature,respectively?

Thanks!

Regards, ann

STN. sea level pressure means the pressure gage at the sea shore

The see level pressure varies normally between about 95000 and 105000 Pa. An average value for the world is 101325 Pa. The pressure is decreasing with height above sealevel with about 100 Pa/8 m.

This is the recognized standard messurements

Pressure: At 45 Degree Latitude at the sea-level height at 20C temp the pressure shown by the pressure gauge is called the standard (sea-level) pressure. Barometer shows at this place 76cm Hg pressure, pressure gauge shows 0 atm and absolute pressure at this area is 101kpa (approx). So far I know there is no standard sea-level temperature.....but standard temp is 0C or 273.15K.
