Label | Explanation | Data Type |

Input Multidimensional Raster | The input multidimensional raster dataset. | Raster Dataset; Raster Layer; Mosaic Dataset; Mosaic Layer; Image Service; File |

Variables [Dimension Info] (Description) (Optional) | The variable or variables for which anomalies will be calculated. If no variable is specified, all variables with a time dimension will be analyzed. | String |

Anomaly Calculation Method (Optional) | Specifies the method that will be used to calculate the anomaly. - Difference From Mean—The difference between a pixel's value and the mean of that pixel's values across slices defined by the interval will be calculated. This is the default.
- Percent Difference From Mean—The percent difference between a pixel's value and the mean of that pixel's values across slices defined by the interval will be calculated.
- Percent Of Mean—The percent of the mean will be calculated.
- Z-score—The z-score for each pixel will be calculated. A z-score of 0 indicates the pixel's value is identical to the mean. A z-score of 1 indicates the pixel's value is 1 standard deviation from the mean. If a z-score is 2, the pixel's value is 2 standard deviations from the mean, and so on.
- Difference From Median—The difference between a pixel's value and the mathematical median of that pixel's values across slices defined by the interval will be calculated.
- Percent Difference From Median—The percent difference between a pixel's value and the mathematical median of that pixel's values across slices defined by the interval will be calculated.
- Percent Of Median—The percent of the mathematical median will be calculated.
| String |

Mean Calculation Interval (Optional) | Specifies the temporal interval that will be used to calculate the mean. - All—The mean is calculated across all slices for each pixel.
- Yearly—The yearly mean is calculated for each pixel.
- Recurring monthly—The monthly mean is calculated for each pixel.
- Recurring weekly—The weekly mean is calculated for each pixel.
- Recurring daily—The daily mean is calculated for each pixel.
- Hourly—The hourly mean is calculated for each pixel.
- External raster—An existing raster dataset that contains the mean or median value for each pixel is referenced.
| String |

Ignore NoData (Optional) | Specifies whether NoData values are ignored in the analysis. - Checked—The analysis will include all valid pixels along a given dimension and ignore any NoData pixels. This is the default.
- Unchecked—The analysis will result in NoData if there are any NoData values for the pixels along the given dimension.
| Boolean |

Input External Raster (Optional) | The reference raster dataset that contains a previously calculated mean for each pixel. The anomalies will be calculated in comparison to this mean. | Raster Layer; Raster Dataset; Mosaic Layer; Mosaic Dataset |
