winds,   tropopause   data,   and   maximum   wind   data. Table 1-8 shows the symbolic representation of the data in Part A, along with examples of coded data. Identification Data In  the  Identification  Data  section  (section  1), example (1) shows typical coded identification data for a fixed land station 1200Z observation on the 14th day of the month from block 72, station 306, with winds in knots. Example (2) shows similar data for a mobile land station:   1200Z observation on the 14th day of the month from site 35.2°N, 078.7° W, Marsden Square 116, with winds  in  knots,  and  a  station  height  of  100  feet. Example (3) is from a ship, the "NSHP" with a 1200Z observation on the 14th day of the month at 31.1° N, 072.1° W, Marsden Square 116, with winds in knots. Example  (4)  is  an  aircraft  dropsonde  directly  over NSHP  at  the  same  time,  except  wind  speeds  are  in meters  per  second. Mandatory Level Data The Mandatory Level data in section 2 contains the bulk of the coded data in this part of the report. The format  for  the  surface  data  is  slightly  different  from  the format for the remaining mandatory atmospheric levels reported  in  Part  A.  The  mandatory  levels  reported  in this part are the surface, 1,000 hPa, 925 hPa, 850 hPa, 700 hPa, 500 hPa, 400 hPa, 300 hPa, 250 hPa, 200 hPa, 150 hPa, and 100 hPa. For  the  surface,  the  three  five-digit  data  groups report  surface  pressure,   temperature   and   dew-point depression,  and  winds. For  each  of  the  mandatory levels,  the  three  five-digit  groups  report  the  pressure Table 1-8.—Part "A" TEMP Coded Upper-Air Report (Surface to 100-hPa Level Mandatory Reporting Levels) S E C SYMBOLIC   FORMAT CONTENTS 1 M_iM_iM_jM_j   YYGGI_d   IIiii Identification  Data Example: (1)  TTAA  64121  72306 (Land   station) M_iM_iM_jM_j   D.   .   .   .D   YYGGI_d   99L_aL_aL_a   Q_cL_oL_oL_oL_o Identification    Date MMMU_LaU_Lo   (h_Oh_Oh_Oh_Oi_m) Examples: (2)  IIAA  64121  99352  70787  11658  01002 (Mobile-land   station (3)  UUAA  NSHP  64121  99311  70721  11612 ( S h i p ) (4)   XXAA   14121   99311   70721   11612 (Aircraft) 2 99P₀P₀P₀T₀T₀T_a0D₀D₀   d₀d₀f₀f₀f₀   (surface) Mandatory  Pressure  Level  data P_nP_nh_nh_nh_n   T_nT_nT_anD_nD_nd_nf_nf_nf_n   (all   other   levels) Example: 99030 05050 09015 00211 06060 09005 92353 02227 08021 85490 00646 07016 70010 06900 08527 50560 22764 09047 40718 33372 09045  30916  459//  09071  25090  543//  09096 20225  581//  09099   15475  595//  09615   10745   575//   09100 3 88P_tP_tP_tT_tT_tT_atD_tD_t   d_td_tf_tf_tf_t   or   88999 Tropopause   data Example: 88225  589//  09098 4 77P_mP_mP_md_md_mf_mf_mf_m  (4v_bv_bv_av_a)  or  77999 Max wind and wind-shear value Example: 77132 09628 40508 1-24
