On the programming of CumulusUtils (2)

Introduction

More than 6 months ago, I wrote a blog  on the how and why of the programming of CumulusUtils. It is time to do that again because in 6 months, over the winter and now deep into the Corona Virus crisis, a lot has happened with CumulusUtils. When I wrote the first blog, it was mainly about the inspiration and development of pwsFWI. And it still is the most important module of the whole program (at least, it is for  me). But while working on pwsFWI and seeing where it was deployed  triggered something. Beside having the pwsFWI, one needs to think about the weather. It is not just a black box, it is about understanding the weather and it’s effect on vegetation and animals (including humans). To understand the weather you need to look at the parameters, the measurements. Continue reading

Predictions of pwsFWI

Introduction

The past months I blogged several times about my Fire Weather Index for personal weather stations on the basis of Cumulus as data acquisition software. So if you’re new here and don’t know what pwsFWI is about, check out the previous blogs on the subject. Currently, pwsFWI is part of a small software package named CumulusUtils. This meteo website/blog is the home of the package which is distributed through the Cumulus support forum. If you have a weather station which can cooperate with Cumulus, don’t hesitate and get it, it’s free.

Behaviour of pwsFWI with first rain

One of the goals of the current implementation of pwsFWI is to see its behaviour under all conditions. It is therefore very interesting to see that behaviour in the two stations in semi-arid zones (in Australia and in Spain) where long dry periods may suddenly alternate with rain after which the drought returns.

On the programming of CumulusUtils

Introduction

Having developed theoretically a Fire Weather Index (see my pwsFWI) and creating a first implementation of it in C for analytical purposes, I needed to take the software a bit further to make it more robust and useful. I had some feedback which made me realize it was urgent to have a good Fire Weather Index (FWI) for Personal Weather Stations (PWSs).

This blog is about the context and the actual programming requirements.
