a 1 wire hum sensor is something that plugs into a spare com port, on the pc, with a 1 wire adaptor, and then you configure WD to use the readings from that…
i think you are worrying too much about cloud height, its not meant to be taken as gospel
Oldun,
I have a La Crosse WS-2310 which is notorious for it’s Humidity deficiencies, Only reports 20% - 96% for starters…
So I added a 1-wire Humidity sensor that I got from AAG, though now that Eric at Hobby-Boards has cases I would buy one from Him if I had to replace…
WD Gives you the ability to mix (add 1-wire) sensors and chose what is reported as your main station humidity, so while I run a La Crosse the Humidity comes from a 1-wire sensor, and also my wind speed is also from another 1-wire sensor…

Hmmm, my dewpoint is less than current temp and I am in the clouds…WD shows 1630 ft for cloud level…I am at 1309 ft. The cloud level should be below my height…going to put my figures in the calculator and see what it shows…hmmm, shows 1636 ft. Strange.
so what it means is that the clouds should be 300 feet above you
Yea, the dewpoint should be higher it seems to me…
Hi all,
I am sure the cloud height reported in metar’s is above ground level (AGL) and NOT above mean sea level (MSL).
I have never seen in a metar, a negative altitude reported as the base for a cloud.
When the computed MSL altitude for cloud height is below the altitude of the station, it simply means the air is saturated. More it’s below altitude station, more it’s saturated.
In aviation, what imports pilots is to know the altitude above the ground at which they will break out of the clouds.
have read that in aviation books.
By the way the altitude reported in Client Viewer is AGL. It just substract Ground level value from MSL cloud height value I presume ( so, it’s correct in my opinion).
In aviation, height is above ground level and altitude is above Mean Sea level.
Sincerely.
It should be possible to show cloud height from sea level rather than height above the station? Even so, with the numbers I had it showed the cloud height above my location. The only way I could see to alter the elevation of the clouds that day was to raise the dewpoint above the current temp, resulting in a negative number in the formula.
