Section 3: READ62 Upper Air Preprocessor Table 3-2 (continued) READ62 Control File Inputs Input group Variable Type Description (1) LHT Logical Height field control variable. If LHT = T, a sounding level is eliminated if the height field is missing. IF LHT = F, the sounding level is included in the output file but the height field is flagged with a "9999", if missing. LTEMP Logical Temperature field control variable. If LTEMP = T, a sounding level is eliminated if the temperature field is missing. If LTEMP = F, the sounding level is included in the output file but the temperature field is flagged with a "999.9", if missing. LWD Logical Wind direction field control variable. If LWD = T, a sounding level is eliminated if the wind direction field is missing. If LWD = F, the sounding level is included in the output file but the wind direction field is flagged with a "999", if missing. LWS Logical Wind speed field control variable. If LWS = T, a sounding level is eliminated if the wind speed is missing. If LWS = F, the sounding level is included in the output file but the wind speed field is flagged with a "999", if missing. LXTOP Logical Extrapolate missing data to from PVTOP to PSTOP (constant wind and temperature). T: Yes- F: No PVTOP Real Minimum pressure above which sounding is extrapolated (if missing) LXSFC Logical Extrapolate missing data down to surface (lowest wind speed extrapolate down with neutral power law. - Temperature is not extrapolated). T: Yes- F: No ZVSFC Real Maximum elevation (m) of the first valid data for extrapolation to the surface 3-6

READ62 processes soundings from standard NCDC d<strong>at</strong>a form<strong>at</strong>s, reports<br />
