This site is made with CumulusUtils, a generator tool for HTML presentation of weather data, retrieved from a weather station powered by CumulusMX. CumulusUtils is originally built by Hans Rottier. It can be freely used and distributed under the GNU GPL license (see Licenses). You can find it here.

It has a wiki of its own: go here.

All versions can be used as a website generator but for the single modules as well. CumulusUtils is for cooperation with CumulusMX.

CumulusUtils stands on the shoulders of the following (but is unrelated to):

• CumulusMX by Steve Loft (retired). Now maintained by Mark Crossley who also did the Gauges (based on the Steelseries). Beteljuice†, user on the Cumulus forum, who, often unsollicited, provided advice and ideas. He made a large range of PHP/javascript tools to enhance the basic sites.
• Ken True of Saratoga Weather (Read the About of that site!), Murry Conarroe of Wildwood Weather had something to do with it.
• Many sites I visited showed an enormous diversity and originality and therefore generated ideas. Look here for a list of sites (the first 15), carrying CumulusUtils (or part of it), which inspired and contributed to the development and testing of the tool. Notably Phil’s Backyard, which quickly became my first test site in the fire summer of 2020 in NSW Autralia. Thanks Phil! Also PaulMy's 'Komoka' played an important role closely followed by Kocher.es and Meyenheim which showed the way for the statistics. And last but not least Mark Crossley's site.
• Finally, FWIcalc by Graeme Kates. FWIcalc, has been developed (from 2002 to 2014) by Graeme Kates in New Zealand, on the basis of the FWI (Fire Weather Index), developed in Canada and also used in New-Zealand and France. Some other indices like the Angstrom and the CBI (Chandler Burning Index) are calculated by FWIcalc as well. Although pwsFWI has theoretically nothing to do with FWIcalc, it definitly is linked to it from a genealogists point of view.
