SPEI 90 Day vs. SPEI 2 Year
This tutorial walks you through requesting different time-period Standardized Precipitation Evapotranspiration Index (SPEI) rasters for the entire US. It uses the GRIDMET DROUGHT dataset and the variables where climatic water balance was aggregated for the last 90 days and last two years. Once the requested rasters are in your google cloud storage bucket, it walks you through copying those into your COLAB files to generate a map. You will need to update the script with three values to run: 1) Insert your API Key, 2) Insert your Google Cloud Storage Bucket, 3) Insert your Project ID.

Land Surface Temperature Trend
This tutorial walks you through requesting a slope of trend (Sen's Slope) raster for Land Surface Temperature (LST) for the entire US. It uses the MODIS Terra 8 day dataset and calculates the trend using the yearly mean between April and September. Once the requested rasters are in your google cloud storage bucket, it walks you through copying those into your COLAB files to generate a map. You will need to update the script with three values to run: 1) Insert your API Key, 2) Insert your Google Cloud Storage Bucket, 3) Insert your Project ID.

GIF Map
This tutorial walks you through generating a GIF map for storytelling and data visualization. Once the requested rasters for the GIF are in your google cloud storage bucket, it walks you through copying those into your COLAB files to generate a series of maps. Then the series of maps will be converted into a GIF. You will need to update the script with three values to run: 1) Insert your API Key, 2) Insert your Google Cloud Storage Bucket, 3) Insert your Project ID.

Time Series
Snotel Stations
This tutorial walks you through requesting SNODAS Snow Water Equivalent (SWE) and Snow Depth time series for all of the active Snotel Stations in the continental US and exporting them to your google drive. As part of a for loop, this tutorial generates csvs and plots for every station. You will need to update the script with your API Key to run the notebook.

Long-term vs. Short-term Blends
This tutorial walks you through requesting Long-term and Short-term Blend data for a point and generating a two-variable plot. You will need to update the script with your API Key to run the notebook.

Chart GIF
This tutorial walks you through generating a GIF chart for storytelling and data visualization. For this example, we use a Earth Engine hosted state boundary dataset and the RAP Annual Forb & Grass Cover dataset. You will need to update the script with your API Key to run the notebook.

Compare ET Models
This tutorial walks you through pulling timeseries data for different ET models available through OpenET for multiple areas of interest. We walk through making the API requests, exporting them as csv, and plotting them as png. For this example, we use a small example boundary dataset and the models available through OpenET. You will need to update the script with your API Key to run the notebook.

Plot Groundwater Level vs NDVI/PPT
This tutorial walks you through pulling timeseries data at well locations to plot groundwater level vs NDVI and Precipitation at that location. We walk through requesting June-July-August NDVI and water year precipitation with the Climate Engine API, retrieving yearly well data from the USGS NWIS and applying additional processing to get June-July-August groundwater level, and then plotting them and adding trend lines. You will need to update the script with your API Key to run the notebook.
