3.2 SELECTING UPPER AIR SOUNDING LEVELS (10/19/07)

The AERMET meteorological processor requires full upper air soundings (radiosonde data)

representing the vertical potential temperature profile near sunrise in order to calculate

convective mixing heights. For AERMOD applications within the U.S., the early morning

sounding, nominally collected at 12Z (or UTC/GMT), is typically used for this purpose. Upper

air soundings can be obtained from the Radiosonde Data of North America CDs for the period

1946 through 1997, which are available for purchase from the National Climatic Data Center

(NCDC). Upper air soundings for the period 1994 to the present are also available for free

download from the Radiosonde Database Access website (http://raob.fsl.noaa.gov/).

Both of these sources of upper air data offer the following three options for specifying which

levels of upper air data to extract:

 

n151 - n152 - n153 - n154 - n155 - n156 - n157 - n158 - n159 - n160 - n161 - n162 - n163 - n164 - n165 - n166 - n167 - n168 - n169 - n170 - n171 - n172 - n173 - n174 - n175 - n176 - n177 - n178 - n179 - n180 - n181 - n182 - n183 - n184 - n185 - n186 - n187 - n188 - n189 - n190 - n191 - n192 - n193 - n194 - n195 - n196 - n197 - n198 - n199 - n200
