“…The vapour pressure derived from the master functions will automatically be self-consistent with other properties. Many other formulae for the vapour pressure of ice have been published: Washburn (1924) is historically important; Jancso et al (1970) combines experimental and thermodynamic data; Buck (1981) is primarily an attempt to find more convenient mathematical forms rather than an independent derivation. See appendix A for a compilation of many of these expressions.…”

SUMMARYThe vapour pressures of ice and supercooled water are reviewed with an emphasis on atmospheric applications. Parametrizations are given for the vapour pressure, molar heat capacity, and latent heat of vaporization of both ice and liquid water. For ice, the experimental vapour pressure data are in agreement with a derivation from the Clapeyron equation. Below 200 K cubic ice may affect the vapour pressure of ice both in the atmosphere and in the laboratory. All of the commonly used parametrizations for the vapour pressure of supercooled water are extrapolations that were not originally intended for use below the freezing point. In addition, the World Meteorological Organization definition of the vapour pressure of supercooled water contains an easily overlooked typographical error. Recent data on the molar heat capacity of supercooled water are used to derive its vapour pressure. Nevertheless, the uncertainty is such that measurements of the deliquescence and freezing behaviour of aerosol particles are beginning to be limited by uncertainties in the thermodynamics of supercooled water.

Introd uctionIn meteorology , air conditioning, a nd hygrometry, parti c ularly in the maintenance and use of standards and generators in calibrations and in prec is ion meas ure me nts, accurate values of the vapor pressure of the pure wa ter-s ubstan ce are essential. Because of this Wexle r and Greenspan [1]1 rece ntly published a ne w vapor pressure fo rmulation for the pure liquid phase, based on th e rm ody namic calc ulations, whic h is in excell e nt agreement from 25 to 100 DC with the prec ise measu reme nts of Stimson [2]. Wexler [3 ] s ubsequently re vised this formulation to ma ke it consis te nt with the defi nitive experi mental value of the vapor pressure of water at its triple point obtained by Guildner, Joh nson, and Jones . The purpose of this present paper is to apply a similar method of calculation to the pure ice phase and derive a ne w formulation for temperatures down to -100 DC. This new formulation for ice is constrained to yield th e id e ntical value of vapor pressure at the triple point as that given by the revised formulation for the liquid phase.A critical examination of the experimental vapor-pressure data of ice discloses the disconcerting fact that the dispersion among those values far exceeds modern accuracy re quirements. This dispersion arises, in part , from the inhe re nt difficulties ex p eri e nced by investigators in making precision measureme nts of these low pressures and from th e ambiguities in the te mpe rature scale used in th e early 19 00's when several major series of determinations were made. Thermodynamic calculations, based on acc urate thermal data, provide an alternate route to th e determination of vapor pressure. It is therefore not surprising that s uc h calculations have been made repeatedly for ice with varying degrees of success . It is interesting to note that these calculations have been preferred over the existent experimental vapor pressures, primarily because the calculations appear to yield less uncertainty than the measurements . .

“…A thermally conductive silicone paste was used to hold the thermocouple in place and to allow for an accurate determination of temperature. The thermocouple was calibrated daily via reference to the ice frost point [Jancso et al, 1970], as described by Iraci et al [1995]. The correction applied was usually of the order of a few kelvins, and the absolute uncertainty in the corrected temperature measurements was <1.0 K, as determined from repeated measurements.…”

Abstract. Crystalline sulfuric acid tetrahydrate (SAT) has been observed to change phase at temperatures below its melting point, in agreement with recent theoretical predictions of deliquescence. Dissolution of SAT was observed in 63% of experiments expected to show a phase change, leading to formation of a ternary HNO3/H2SOn/H20 solution. This solution, which still contained a portion of the original solid SAT, crystallized to form nitric acid trihydrate (NAT). NAT then continued to grow by condensation of additional nitric acid and water at temperatures several degrees above the ice frost point. This process of SAT dissolution followed by NAT crystallization and growth may offer a mechanism for the formation of type Ia polar stratospheric clouds on frozen sulfate aerosols when SNAT > 15.
