Change Log
Improved
Optimized Leaflet tile-loading pipeline for overlays, reducing map stall events by ~30%.
Enhanced mobile layout for chart controls and polygon drawer tool.
Fixed
- Resolved bug where occasionally daily ETo values displayed in the wrong units.
- Fixed issue where chart tooltips would disappear when quickly mousing between series.
Improved
- Smoothed pan/zoom transitions in geoserver to avoid jitter on large areas.
Fixed
- Fixed rare issue where switching from monthly to daily mode duplicated one date entry.
v2.2.21
2024 Added to Public Data Catalog (Addition)
OpenET monthly model datasets are now available for 2024 in the Google Earth Engine public data catalog.
Geodatabase Queries (Improvement)
The latest updates have significantly reduced latency for large queries, resulting in an average speed improvement of 6.8x or 85% less time for large geodatabase returns.
ETo & Pr Resampling (Fixed)
Fixed an issue which prevented the resampling of 4km to 30m reference ET and precipitation.
v2.1.1
2000-2007 Added to Public Data Catalog (Addition)
OpenET monthly model datasets are now available from 2000-2007 in the Google Earth Engine public data catalog and are now accessible through the API.
Quota Overpass Raster Stack Bug (Fixed)
Fixed an issue where requests count would over estimate number of cloud free days of overpass data.
Export Resolution Handler (Addition)
Data now exports more efficiently at native satellite resolutions for variables like ETo and Pr.
v2.1.0
Count Variable (Model Only Addition)
Added support for retrieving the number of cloud-free satellite observations using the [count] variable in OpenET models. This feature is available exclusively for monthly model collections and not the model ensemble.
Model Count Variable (Ensemble Only Addition)
For the monthly Ensemble collection only, view the number of models contributing to each observation using the [model_count] variable.
Precipitation Bug (Fixed)
Fixed a bug where resampling would run into issues in masked regions along the west coast.
Account Initialization Bug (Fixed)
Fixed a issue which would add additional latency when querying across multiple accounts. This will result in overall faster queries.
Raster Queries Timestep Increase (Improvement)
Enhanced memory handling for daily raster data retrieval via the multipolygon endpoint. Users can now retrieve data for up to 366 timesteps (previously limited to 62), enabling more comprehensive analyses. Be wary of running into memory limits for complex or large areas.
v2.0.5
2008-2012 Added to Public Data Catalog (Addition)
OpenET monthly model datasets are now available from 2008-2023 in the Google Earth Engine public data catalog and are now accessible through the API.
Daily Data Interpolation with different Date Ranges (Fixed)
Fixed a bug where the API would return a different value for interpolated data depending on the date range.
FRET Stack Bug (Fixed)
Fixed a bug where the API would return only the first day of a forecasted reference ET.
Geodatabase Queries (Improvement)
The latest updates have significantly reduced latency for large queries, resulting in an average speed improvement of 1.6x for all geodatabase returns.
Quota Max Area Bug (Fixed)
Fixed an issue where if a query exceeded the users quota an incorrect error message would return.
v2.0.4
Raster Metadata [date_ingested] (Deprecated)
We are updating the metadata keyword from [date_ingested] to [build_date].
2013-2015 Added to Public Data Catalog (Addition)
OpenET monthly model datasets are now available from 2013-2023 in the Google Earth Engine public data catalog and are now accessible through the API.
EECUs Showing 0's (Fixed)
Fixed a bug which was not correctly displaying EECU compute use for exported data.
Super Sampling to 10m (Addition)
Raster image generation now supports 10m resampling for increased fidelity for analysis.
Rapid Query Issue (Fixed)
When querying the API rapidly some requests return a 401 error incorrectly. This is now resolved.
Upload geoJSON (Fixed)
Fixed a bug when using the account/upload endpoint in which the resulting call to retrieve the file would fail during high volume server autoscaling.
v2.0.3
Forecasted Reference ET (Addition)
Using NOAA's FRET product eto data can now be queried for 7 day forecasts. Change [reference_et] to ["fret"] and [date_range] to the current day and 7 days into the future. Note this is experimental and has not yet been fully evaluated for accuracy.
Raster Point & Polygon Daily Data Increase (Improvement)
We've increased the limit from 365 days to 10 years. With large polygons, you can run into memory limits with this update.
v2.0.2
Megaliter Calculation (Fixed)
When using the multipolygon endpoints the hectares and megaliter calculations were off by a factor of 10.
Personal Bucket Export (New Feature)
Exports to a personal Google Bucket are now supported. This new parameter supersedes drive exports even if your Cloud Project is linked.
v2.0.1
Export Return [queue_number] (Deprecated)
Calculating queue placement has become too slow with the latest updates to the Earth Engine API and our growing user base. This return feature has been removed which will on average result in a 42x time reduction when exporting files.
Geodatabase Precipitation (Fixed)
In some areas precipitation data preloaded in the geodatabase was incorrectly projected resulting in erroneous data.
v2.0.0
Duplicate Drive Folder (Bug)
When exporting files to Google Drive, the export folder may be duplicated. As far as we are aware, this is a bug within the latest version of Google Earth Engine's API. Try creating the folder before exporting.
Improved
- Optimized Leaflet tile-loading pipeline for overlays, reducing map stall events by ~30%.
