DROUGHT INDICES – SPI (NDMC experience) • SPI calibration period: how long period to use? • There is no "absolute best" recommended calibration period • Suggestion from NDMC (Nebraska): something like 50 years, ending around 2000; if you don't have as much data history, then adjust accordingly

 · The first term in the equation from the customer is converting peak to peak AC voltage to RMS. For DC measurements, the peakpeak signal is the max code minus the min code which is about the RMS signal. The RMS signal is one standard deviation (one sigma) of the population which contains 68% of the sample set, assuming a gaussian distribution.

balance equation, or 2) the standardized precipitation index (SPI; McKee et al. 1993), based on a precipitation probabilistic approach. The PDSI was a landmark in the development of drought indices. It enables measurement of both wetness (positive value) and dryness (negative values), based on the supply and demand concept of the water balance

ADFMCDAQ2EBZ HDL Reference Design [Analog Devices Wiki]

One important aspect for ADFMCDAQ2EBZ is that the reference clock needed for the FPGA transceiver calibration is generated only after the AD95231 clock generator is configured. The programming is done only after the FPGA is configured and software is running. Because of this, the software needs to perform a transceiver recalibration after ...

 · Taking Henan Province as an example, based on the SPI values of 19 meteorological stations from 1951 to 2017, this study compares the effectiveness of two models in forecasting drought conditions in Henan Province. The multiscale SPI was forecast and compared using a traditional ARIMA model and a hybrid ARIMA–SVR model for 1–6month lead time.

How to calibrate touch screen display on STM32 board

 · Touch screen displays are a common choice in many microcontroller projects. Touch capability won't take additional space – it sits on top of LCD to directly interact with objects you see on screen. To get this working, touch screen coordinates must match screen coordinates. So could be sure when you touch the point on screen you point where you want. The touch screen is an analog device ...

The equation in the notes implies that the relationship is linear, however. So a twopoint calibration should be sufficient, which means taking a reading at two different temperatures and deriving the actual offset and slope through algebra. If you trust the slope value of mV/C you can do a single point calibration.
