Today I added 2 more rain gauges to the weather instrument collection on the website:

• A Weather Measure Model 6330 4-Inch Rain Gauge
• A US Army ML-435 4-Inch Rain Gauge

Go to Rain Gauge Page.

Today I added a section to the Instrument Collection web pages for rain gauges and evaporation meters.  I also posted 3 rain gauges to the website:

1. A 8-Inch US National Weather Service pattern rain gauge made by WS Jenks.
2. A 5-Inch Snowdon rain gauge made in the UK by Casella.
3. A 3-inch rain gauge made by Taylor Instruments.

Go to Rain Gauge Page.

Today I added 3 miscellaneous slide rules for wind, solar and data reporting applications.  I still have some weather forecasting slide rules that I will add to the website in a couple days.

​Go to Meteorological Slide Rule Page.

Today I added 3 pressure/altitude slide rules to the website.  These are really aviation oriented objects but have a meteorological flavor.

​Go to Pressure/Altitude Slide Rule Page.

Today I added 5 psychrometric slide rules to the website.  I moved the slide rules to a separate section of the Instrument Collection webpage.  I have 8 more (non-psychrometric) slide rules that I'll add over the next week or so.

​Go to Psychrometric Slide Rule Page.

Today I added a Casella Model 6100 Campbell Stokes Sunshine Recorder to the instrument collection section of the website.  Go to Casella Sunshine Recorder Page.

I also added an Eppley Model 10 Pyranometer to the website, where it joins the Model 50 Pyrheliometers that were already there.  Go to Eppley Model 10 Page.

Today I added a 9 page excerpt from W M Welch Catalog G showing the meteorological instruments they carried.  Go to the W M Welch Catalog Page.
