*3.2. Bias Correction*

Bias correction is the second component of the ST-CORAbico method. This component is based on the systematic error source extraction for SPP that was proposed by Laverde-Barajas et al. [42]. Based on the error decomposition for storm estimation defined by Ebert and McBride [24], satellite error is composed of systematic and aleatory errors due to displacement, volume, and pattern, as:

$$E\_{total} = E\_{displacement} + E\_{volume} + E\_{pattern} \tag{6}$$

where displacement and volume represent the systematic errors and pattern is the aleatory error calculated as follows:

$$E\_{displacement} = E\_{total} - E\_{shifted} \tag{7}$$

$$E\_{\text{volume}} = E\_{\text{total}} - E\_{\text{magnitude}} \tag{8}$$

$$E\_{pattern} = E\_{shifted} - E\_{volume} \tag{9}$$

In Equations (7) and (8), location is the main source of error due to displacement, while the magnitude is the corresponding source of error for volume. Using the error subtraction from Laverde-Barajas et al. [42], ST-CORAbico corrects displacement and volume error using the following process:
