Glacier runoff projections and their multiple sources of uncertainty in the Patagonian Andes (40-56°S)

This dataset contains the catchment scale results of the study: "Unravelling the sources of uncertainty in glacier runoff projections in the Patagonian Andes (40–56° S)". The results are disaggregated in the following files (for more details, please read the README file): - basins_boundaries.zip: Contains the polygons (in .shp format) of the studied catchments. Each catchment is identified by its "basin_id". - dataset_historical.csv: Summarises the historical conditions of each glacier at the catchment scale (area, volume and reference climate). - dataset_future.csv: Summarises the future glacier climate drivers and their impacts at the catchment scale.  - dataset_signatures.csv: Summarises the  glacio-hydrological signatures of each glacier at the catchment scale.

Projected distribution of invasive plant species in the tropical Andes under climate change

Distribution maps of 11 invasive species now and in the future (2040-70). The projections were the result of the assembly of three algorithms: Adaptive Boosting (AdaBoost), Boosted Regression Trees (BRT), and Extreme Gradient Boosting (XGBoost). Future projections were made for three global circulation models and three climate change scenarios, each with low (SSP126), medium (SSP370), and high (SSP585) levels of carbon emission. Habitat suitability and presence/absence maps are also included. The threshold for establishing a species as present was determined to be the value that maximized the TSS.  For more information, see the article accompanying the dataset by González-Trujillo et al.

The files in this set are data obtained from the ANI2 airglow imager located at the Andes Lidar Observatory.in Chile (30.23S, 70.73W, 2530 m). The files are  named for a JGR paper by J. Hecht et al.  entitled A "Boreing" Night of Observations of the UpperMesosphere and Lower Thermosphere Over the Andes Lidar Observatory. The files are published here so as to be available for review. This paper should appear in JGR Atmospheres sometime in late 2023 or early 2024. The files that  are text files are meant to be  read with IDL as discussed in the readme file.
