<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;"><DIV>Something that has been on my wishlist for some time now is a "It's Raining Now" flag. All the</DIV>
<DIV> rainfall fields are after the fact, or how much it HAS rained. I'd also like to see a "Rate of</DIV>
<DIV> Rainfall" field. In a heavy rain the console of my Davis Vantage Pro2 wil say "It's rainging Cats</DIV>
<DIV> and Dogs" so I know the data is in there. Just need a field to put it in and a software update</DIV>
<DIV> from Davis to output it to APRS. Thinking about it more, if there was just a "Rate of Rainfall"</DIV>
<DIV> field then anything above 0 (zero) would mean it's raining now.</DIV>

<DIV>The original APRS defines SNOW Sxxx and LUMINOSITY Lxxx fields<BR>for the weather format, and I thought it included visibility<BR>Vxxx, though I cannot find it right now. Does anyone recall if<BR>anyone uses these. If not, I propose a Vxxx field if someone<BR>can recommend the right units.<BR><BR>Lets look at this original APRSdos file:<BR><BR>www.aprs.org/APRS-docs/WX.TXT see extract below<BR><BR>And it appears to cover Snow, but not Visibility. Though I was<BR>sure I had proposed Visibility at some time or other.... SO<BR>check the original spec, or the addendum<BR>www.aprs.org/aprs11.html and there find this link:<BR><A href="http://www.aprs.org/aprs11/spec-wx.txt">http://www.aprs.org/aprs11/spec-wx.txt</A><BR><BR>><I> FORMATS: APRS re-formats data from attached WX units <BR></I>><I> and transmits the data as shown below.
