Firstly just a quick note to say that this is my first month since Sep 2001 that I have not broken any records!
Hail Reports
~ Mon 3rd - I received pea sized hail for ~3mins from ~1620. This come from rapidly moving storms toward the E.
Recent Additions to Statistics List
~ I have recently thought of a way & written the file for converting the FreeWX 'grafdata.dat' file into a more legible
format. This will mean I will be able to analyse events much more closely & efficiently. It also means that I will be
able to add a column to my FreeWX log file for recording 10min gusts. I have analysis for 1 & 10min data as well as
several graphs. This file will also be available on my 'Weather Calculator' page toward the bottom shortly.
Instrument Additions
~ Rain Gauge (Hydrological services TB3 with 0.2mm buckets) - I took delivery of this little beauty during Sep & hope to
have it installed within the next few weeks. I also purchased a data logger for use as a backup. With this gauge I am
hoping I will be able to connect it into my AWS & have this higher quality rainfall data uploaded onto my website in
place of my current sub-standard AWS rain gauge. Preliminary tests of this look very positive!
Instrument Alterations (August)
~ On the 14th I adjusted my weather cam to capture images every 10mins instead of every 5. The idea for this is to
increase the life of the camera. Further to this, on clear days images are only captured at 30min intervals. Uploads to my
website are still every 30mins during daylight hours.
On the occurance of interesting weather however I will (if home) take captures at much more regular intervals & also
upload each of these to my website. An example of this occurred on the 3rd when I was capturing & uploading images
at 5min intervals.
