_D_e_s_c_r_i_p_t_i_o_n:

     Six years of monthly pressure and high cloud cover measurements
     over a regular grid of the Americas, from NASA's poster
     competition at the 2006 Joint Statistical Meeting (JSM).

_F_o_r_m_a_t:

     This NASA data set is stored as a list of 3 components: 'data'
     (containing the pressure and high cloud cover measurements),
     'elev' (the elevation data), and 'coast' (the coastline data).  To
     see the structure, type 'str(nasa)', and see 'Details' and
     'Source' for more information, below.

_D_e_t_a_i_l_s:

     The data are a subset of some geographic and atmospheric
     measurements on a coarse 24 by 24 grid covering Central America.
     The variables included are elevation, air pressure, and high cloud
     cover. With the exception of elevation, the variables are monthly
     averages, with observations for Jan., 1995 to Dec., 2000. These
     data were obtained from the NASA Langley Research Center
     Atmospheric Sciences Data Center.
