We have recently completed a series of measurements studying the temperature dependence of water vapor absorption in the $10\mu m$ region using a frequency stabilized $CO2$ laser in conjunction with both a differential spectrophone and a 15 meter White cell. This work was performed with both pressure broadened and pure water vapor samples over a temperature range from $15\circ$ C to $28\circ$ C. Recent work in the study of temperature dependence for the water vapor continuum in the $8-12\mu m$ window are compared with those results and a new improved model is given.
