MESOPAC is a mesoscale meteorological preprocessor program; it is designed to provide meteorological data to regional-scale air quality simulation models. Radiosonde data routinely available from National Weather Service (NWS) radiosonde ('upper air') and surface stations are used to produce spatially-interpolated, time-sequenced mesoscale meteorological data fields. These include: (a) horizontal (u,v) wind components; (b) mixing depth; (c) Pasquill-Gifford-Turner (PGT) stability class. An interpolation/iterative relaxation scheme is used to construct the wind field. The mixing depth and PGT stability fields are created with a new physically appealing algorithm. MESOPAC is a fully-independent program, easily coupled to any reasonably modular transport-diffusion model. Currently, it is used to drive the MESOPUFF, MESOPLUME, and MESOGRID models. MESOPAC is highly user-oriented: easy to understand; easy to use; easy to modify. If offers a range of features including: user-specified grid resolution (maximum resolution is 40 x 40 elements); arbitrary grid orientation and size; user-specified data stations and significant data levels (e.g., surface, 850 mb, 700 mb); user-controllable minimization of wind field divergence; time-weighted (centered) interpolation of data fields; arbitrary duration of meteorological episode; and multiple choices of output time interval (1, 2, 3, 4, 6, or 12 hours).
