Mesonet Data From Mapleton, Iowa Tornado – April 9, 2011
First, let me preface this with the following: my homemade instrumentation is by no means intended as a substitute for scientific grade research equipment. I certainly did not go out and spend thousands of dollars on research grade equipment, nor did I spend hours and money on scientific calibration techniques. What I did is collect a bunch of decent sensors which had decent specifications befitting of someone who wanted to collect data in the field and check it out later. Before taking it out in the field, I compared it with ASOS readings nearby and was usually within a degree on temperature, a percent or two on humidity and 1 hPa on pressure. I considered that good enough for my purposes. You can review the parts I’ve selected for my measurements in my mesonet build project posts earlier on this blog.Read more
