Centre county Pennsylvania, USA | Simple regression analysis on the most recent 55 years of NASS and NOAA data shows that 93 % of national corn yield can be explained by NASS national corn trend yield and NOAA June through July climate temperature anomaly in the US corn belt. That doesn't mean that corn yield in each of our corn fields can be predicted by that field's trend yield and it's June through July climate temperature anomaly, but it's probably worth investigating. The big problem with climate is finding reliable and accurate climate data. Because the climate data we would need for each of our corn fields is climate temperature anomaly for 2 months (June through July) of each year, it is feasible to collect our own climate data each year in each of our corn fields.
Thanks to the micro-controller and lithium ion battery revolution, very small, accurate, and autonomous, climate temperature and humidity data loggers are available at reasonable cost. Those data loggers are capable of measuring and logging temperature, humidity, and calculated dew point, at 30 minute intervals for an entire year (365 days). The attached screenshot shows one such climate data logger and a short (2day) test run of it's capability. For that test run, the climate data logger was placed inside our grain system's climate controlled power shed (GAC Shack).
