DATA RECORDS (repeated for each grid cell in extraction subdomain)
Data Record
Variable Type Description
1 MYR integer Year of MM5 wind data (YYYY)
2 MMO integer Month of MM5 wind data (MM)
3 MDAY integer Day of MM5 wind data (DD)
4 MHR integer Hour (GMT) of MM5 wind data (HH)
5 IX integer I-index (X direction) of grid cell
6 JX integer J-index (Y direction) of grid cell
7 PRES real sea level pressure (hPa)
8 RAIN real total rainfall accumulated on the ground for the past
hour (cm)
9 SC integer snow cover indicator (0 or 1, where 1 = snow cover was
determined to be present for the MM5 simulation)
10* RADSW real Short wave radiation at the surface (W/m**2)
11* RADLW real long wave radiation at the top (W/m**2)
12* T2 real Air temperature at 2 m (K), zero or blank if not exist
13* Q2 real Specific humidity at 2 m (g/kg), zero or blank if not
exist
14* WD10 real Wind direction of 10-m wind (m/s), zero or blank if not
exist
15* WS10 Real Wind speed of 10-m wind (m/s), zero or blank if not
exist
16* SST real Sea surface temperature (K), zero or blank if not exist
format(i4,3i2,2i3,f7.1,f5.2,i2,3f8.1,f8.2,3f8.1)
* Set to all zero if not existing in output of MM5 or other models
MM5 Note: WD10 and WS10 are MM5 output at dot points, other meteorological variables are
interpolated in CALMM5 to dot points from MM5 output at cross points.
