The station circle represents the cloud cover; open circle means clear; and a completely covered circle means 100% cloud cover (or fog). The line extending outward from the station circle is called a wind barb and represents the wind flow; where the wind is blowing from the direction of the barb (north is towards the top of the map and east is towards the viewer's right). The line(s) extending from the end of the barb are called feathers and represent the windspeed.

The square symbol is reserved for automated stations. An automated report is signalled by either "AUTO", "ASOS", or other similar abbreviations in the report, or by the indicator for automated observations in a SYNOP report. Digital Atmosphere will let me perform one Barnes analysis, but if I try to perform a second Barnes analysis I receive a Range Check error. Examine File > Preferences > Analysis > "Figure geostrophic heights".

Surface Fronts describes the fronts depicted on our analysis and forecast maps, along with how to interpret the 3-letter coding adjacent to the frontal boundary. Precipitation Areas explains the weather symbols and the difference between shaded and unshaded precipitation areas used on our short range (1-2 day) forecasts. The valid time for this product varies slightly depending on the weather feature for which you are interested.

We do not have this explanation on our Web site, but it can be found elsewhere on the Internet. You may try the following sites: Synoptic code Table, from a British site which is to be consulted in conjunction with this other site.

See our plot reference sheet at wxcode1.gif (weather) and wxcode2.gif (clouds). These images are extracted from our Weathergraph reference sheet. In Digital Atmosphere 2000, when I display a station plot, I only get the oktas, wind barb, pressure and ceiling height. No temperature, no dewpoint, no visibility. I checked the preferences immediately, and all of the fields are there.

We actually have two different weather station equipment online, one being the LaCrosse 2315 and the other being a Dallas 1-wire with custom sensors.

A red station plot indicates instrument flight rules (IFR), which means the ceilings are below 1000 feet and/or the visibility is below 3 miles. A blue station plot indicates marginal visual flight rules (MVFR), meaning the ceiling is below 3000 feet and/or the visibility is below 5 miles. These colors are good for helping you visualize areas of low ceilings and visibility at a glance.

The weather station is mounted on the roof of the Earth Sciences Building at Palomar College. Ideally, an official weather station would be mounted approximately four feet above a "natural" surface (grass, soil, etc.), but the rooftop location provides us a convenient, out-of-the-way location. The instruments report through cables to monitors in ES-16 (the seismograph room).

Each symbol is composed of the first two letters of the genus+first two letters of the species+first letter of the terminal infraspecific name+tiebreaking number (if needed). Genus and family symbols are the first five (genus) or six (family) letters of the name, plus tiebreaking number (if needed). Symbols were first used in the Soil Conservation Service’s National List of Scientific Plant Names (NLSPN), and have been perpetuated in the PLANTS system.

Make sure the symbol line color is different from the symbol fill color. Open the symbol map properties, click the button in the symbol group, and then check the line and fill colors in the symbol properties dialog box.

A number symbol (#) before an entry number indicates that it is a descriptive entry, usually of a phenotype, and does not represent a unique locus. The reason for the use of the #-sign is given in the first paragraph of the entry. Discussion of any gene(s) related to the phenotype resides in another entry(ies) as described in the first paragraph. A plus sign (+) before an entry number indicates that the entry contains the description of a gene of known sequence and a phenotype.

They actually do not represent any rises in sea level or changes in weather patterns, that we know of.

Alot of maps are being renovated. LoA has currently 2000+ maps, and about 350 have been redone. It's a work in progress.

These are the same weather maps that are used by weather forecasters in the US and around the world. However, FlightAdventures only provides weather maps for informational purposes only. For navigational weather, please refer to DUATs or directly to a FSS.

Every weather map has a time and date stamp on them. But once again, FlightAdventures only provides weather maps for informational purposes only. For navigational weather, please refer to DUATs or directly to a FSS.

Our station is Model WS-1000TM, commercially available from RainWiseTM. RainWise manufactures a complete line of consumer and industrial meteorological measuring and recording instruments. The Wind Direction, Wind Speed and Rainfall weather sensors are combined into a rooftop unit that is easily mounted on a standard TV antenna mast. Maximums and Minimums are recorded and stored for Outside Temperature and Barometric Pressure.

The weather station data here is located in Makakilo, Hawaii, on the island of Oahu, approximately 25 miles from Honolulu. We are at about 350 feet of elevation and on the leeward (dry) side of Oahu. Leeward Oahu receives significantly less rain than other parts of Oahu and on average is warmer during the day by a few degrees as well.
