Minor bug fixes for version 3.0.1.1 (Posted 1/9/09)
Bug fix related to check_rh=2
To fix this problem a second RH check have been added after the moisture adjustment to
ensure the RH is within a reasonable range.

Bug fix related to sfc_assi_options=1
To keep original (not WRF-Var "corrected" when sfc_assi_options=1) surface pressure for writing out in gts_omb_oma and filtered_obs.
Note: when qc_flag=2, O-B (Observation minus Background) values are calculated from surface-"corrected" O, while O values written out in gts_omb_oma are original values. That means B values are unknown when qc_flag=2.

Bug fix related to analysis_type = "VERIFY"
This fix will ensure the writing out of statistics.

Bug fix to initialize jo_radiance properly when radiance code is not included.

All the above bug fixes and other minor fixes are available as a patch.
This file needs to be untarred in the main WRFDA directory.
Known Problems for version 3.0.1.1 (Posted 1/9/09)
WRF-Var does not work properly with NCEP PREPBUFR observations, because of the following known problems:
(1) pressure fields are used twice and observation numbers are double-counted because mass and wind reports are separated in NCEP PREPBUFR files.
(2) time-duplicate observations from fixed stations are over-used. For ex maple, there are more than one synop report from a surface station contained in a 6-hour time-windowed PREPBUFR file, only one report should be used.
Fixes will be available in the next release.
Known Problems in Version 3.0.1 (details)
Compile Error using PGI 7.1+ (posted 6/10/08)
