+The contiguous United States (CONUS) Disturbance Watcher system was built based on time-series analysis and machine learning techniques. The system consisted of two components. The first component, the retrospective disturbance analysis, extracted disturbance predictors from historical open access disturbance products and satellite datasets and built a series of machine learning models respectively for different lag stages. The second component, namely the near real-time monitoring, recursively updates per-pixel time-series models and outputted current vectors of disturbance predictor using Stochastic Continuous Change Detection (S-CCD) algorithm, and then applied the offline machine learning models from the first component to map disturbance probabilities and patches. The system could be updated regularly in an interval of one week, or updated as an user-defined interval, such as one day that was used for Hurricane Ian monitoring. The per-day updating interval provided the quickest mapping response and the most extensive damage region as some would be recovered after days, while the highest computational resources were needed.

+The Hurricane Ian disturbance probability layer shows the likelihood impacted by Hurricane Ian. The data came from the map production of [CONUS Disturbance Watcher system](https://gers.users.earthengine.app/view/nrt-conus) on Oct. 3th, 2022, when the first post-hurricane Harmonized Landsat Sentinel-2 (HLS) 2.0 dataset on Sep. 30th, 2022 became available for downloading. The [HLS dataset](https://hls.gsfc.nasa.gov/) produce harmonized surface reflectance products from four satellite sensors, i.e., Landsat-8, Landsat-9,  Sentinel-2A and Sentinel-2B, providing observation once every 2-3 days. The probability layer (scaled by 100) describes the probability produced by machine learning models. The higher probability reveals the high spectral similarity to the historical disturbance.

+Harmonized Landsat Sentinel-2 (HLS) project from NASA is designed to integrate and harmonize data from multiple satellite sources, specifically the Operation Land Imager (OLI) on Landsat-8/9 and the Mult-Spectral Instrument (MSI) on Sentinel-2A/B satellites. This project aims to create a seamless surface reflectance record that is essential for various Earth Observation and monitoring tasks.

+**Scientific Details:**  
+HLS project incorporates several advanced scientific methodologies and technologies to harmonize data from the Landsat and Sentinel-2 satellites such as atmospheric correction, geographic co-registration and common gridding, bidirectional reflectance distribution normalization, and cloud-shadow masking. The calculation of entropy can be accomplished using the 'entropy' function from the 'scipy.stats' module, which computes the entropy of a distribution for given probability values. This function calculates the Shannon entropy. This metric quantifies the randomness or unpredictability inherent in the dataset's distribution from one time point to another.

To calculate the Normalized Difference Vegetation Index (NDVI) from the HLS-2 Dataset, we utilize the red and near-infrared bands to assess vegetation health by applyin the formula NDVI = NIR - Red / NIR + Red, where 'NIR' refers to the near-infrared surface reflectance, and 'Red' denotes the red light surface reflectance, both harmonized from the Landsat and Sentinel satellites.
