Re: radar colors for winter

Post by severe storm_forecaster »

Hello list,

I had an idea about changing the reflectivity colors into a winter scale, but when I took a look at the digatmos.nex file, I began having doubts about this. I know what "RA" means but "RB" stumps me. I have no clue how to do this, so anyone who can help me attempt this would be appreciated.

Here is what I did do with my digatmos.nex file so far. It's the "winterscheme" at the bottom of the list.
----------------
# SCHEME NUMBERS
#
# SCHEME=000 Normal
# SCHEME=001 Normal - alternate clear air
# SCHEME=002 College of DuPage
# SCHEME=003 WSR-88D OEM PUP
# SCHEME=004 Weathertap
# SCHEME=005 Black and white
# SCHEME=006 Winterscheme
#
# Nexrad product codes: http://www.nws.noaa.gov/tg/radfiles.html
#
# Set RRGGBB ------ to force color to not plot
#

#COD PRM VAL RRGGBB VALUE (NOT USED)

nexrad radar

Post by Ross »

I believe that that is for when the radar is in clear air mode. Example I set the first eleven values to my back ground color to cut down on clutter when the radar is in this mode.

Hi Ross:

Thanks for the reply. Can you send me a snippet of what you mean? I think I know what you could mean, but need clarification. Then, how would I use those colors for when the radar is in precipitation mode? My backround color is black, by the way.

Thanks,
Randy

Hi Randy
First off I have to mention that I am still using DAWS and not Equinox,
there are some slight differences in the digatmos.nex
In DAWS I use this in the .nex file:

################################################
# My_Scheme #
################################################
006 RA 000 000000 0 # AWIPS
006 RA 001 000000 5
006 RA 002 33FFCC 10
006 RA 003 00FFFF 15
006 RA 004 00ff99 20
006 RA 005 00ff00 25
006 RA 006 99ff00 30
006 RA 007 FCF800 35
006 RA 008 E4C0E4 40
006 RA 009 FC9090 45
006 RA 010 FC0000 50
006 RA 011 D40000 55
006 RA 012 C00000 60
006 RA 013 FC00F8 65
006 RA 014 9850C8 70
006 RA 015 FCF8F8 76

006 RB 000 000000 0
006 RB 001 000000 5
006 RB 002 000000 10
006 RB 003 000000 15
006 RB 004 000000 20
006 RB 005 000000 25
006 RB 006 000000 30
006 RB 007 000000 35
006 RB 008 000000 40
006 RB 009 000000 45
006 RB 010 000000 50
006 RB 011 00FFFF 55
006 RB 012 00FFFF 60
006 RB 013 00FF99 65
006 RB 014 00FF00 70
006 RB 015 99ff00 76

In Equinox I would just copy the default scheme in the .nex file, it has changed from DAWS, and renameit as in:

###################################
# Winter SCHEME #
###################################

006 RA 000 000000 0 # NEW

006 RA 013 F800F8 65
006 RA 014 9050C0 70
006 RA 015 F0F0F0 76

006 RB 002 ------ -24

006 RB 004 ------ -16
006 RB 005 ------ -12
006 RB 006 ------ -8
006 RB 007 ------ -4
006 RB 008 ------ 0
006 RB 009 00E0E0 4
006 RB 010 00E0E0 8
006 RB 011 08A0F0 12
006 RB 012 0004E7 16
006 RB 013 00F800 20
006 RB 014 00F800 24
006 RB 015 00C800 28

Then just change the color values to what you want.
I use this site for color reference http://www.web-source.net/216_color_chart.htm
It gives you the hexadecimal values you need.
RA values should be the precip mode
RB values should be the clear air mode
I think...........not an expert here may be someone else can chime in...

Hi again Ross:

Thanks for your input. I did not realize there were differences either. I think I'll just use your wisdom and try to get this to work. I hope!!!

Thanks,
Randy

Hi Ross:

I did as you suggested, and now it plots everything black, even the scale shows all levels black. Here is what I did:

I know you said you were unsure of some of this, but why should it plot all black when there is no color black in the color codes? Also, can you send me a copy of the .nex file again? This one is all messed up.

Thanks,
Randy
