        abstract:  The Rainfall Rate Quantitative Precipitation Estimate (QPE) product contains an image with pixel values identifying the rainfall rate. The product includes data quality information that provides an assessment of the rainfall rate data values for on-earth pixels. The units of measure for the rainfall rate value is millimeters per hour. The Rainfall Rate (QPE) product image is produced on the ABI fixed grid at 2 km resolution for the Full Disk coverage region. Product data is produced for geolocated source data to local zenith angles of 90 degrees for both daytime and nighttime conditions.
        purpose:  The ABI Rainfall Rate algorithm generates the baseline Rainfall Rate product from ABI IR brightness temperatures and is calibrated in real time against microwave-derived rain rates to enhance accuracy. The algorithm generates estimates of the instantaneous rainfall rate at each ABI IR pixel. The information provided by the QPE will be used by forecasters and hydrologists in flood forecasting. Much of the flooding that occurs is related to some form of convective weather. The higher spatial and temporal resolution available on the GOES-R ABI will be able to automatically resolve rainfall rates on a much finer scale, enabling weather forecasters to produce more timely and accurate flood advisories and warnings.

            processStep:  (LE_ProcessStep)
                description:  The Rainfall Rate (QPE) product is generated by the GOES-R ABI Rainfall Rate (QPE) ground processing algorithm. Rainfall rate is obtained using a two-step process that involves the detection of pixels where rain is occurring and the retrieval of rainfall rate for those pixels. The algorithm includes eight linear and eight non-linear predictors based on brightness temperatures measured in five emissive ABI bands 8, 10, 11, 14, and 15 with central wavelengths of 6.185, 7.34. 8.5, 11.2, and 12.3 um, respectively. As a result of the spectral range of the ABI instrument not being capable of penetrating optically thick clouds where precipitation is occurring, the algorithm uses retrieval coefficients that are established based on a statistical correlation of the observed cloud top brightness temperatures with rainfall occurrence and rate as detected by sources capable of penetrating optically thick clouds, such as microwave observations. The retrieval coefficients used by the algorithm are managed as Level 2+ processing parameters (i.e. semi-static data) in the ground system.
