In a 2024 paper criticizing the 'billion-dollar-disasters' database, Roger Pielke Jr. published analysis that is best described as a Russian-doll of errors.

Here's my in-depth take down of his appallingly bad work.

Roger Pielke Jr.’s Appallingly Bad Analysis of Billion Dollar Disasters – Economics from the Top Down
In a recent paper called Scientific integrity and U.S. “Billion Dollar Disasters”, Roger Pielke Jr. published a chart that's so bad I've devoted a whole essay to debunking it.

Hydrology Paper of the Day @rarakihydro.bsky.social on a model of soil moisture loss that utilizes a nonlinear function: model fitting to SMAP remote sensing data; an examination of global-scale patterns; how aridity, sand fraction and landcover affects outputs; and the role of evapotranspiration.
rarakihydro.bsky.social Ryoko Araki @rarakihydro.bsky.social · Jun 3
My 2nd PhD chapter is out! Soil drying speeds encode the signature of evapotranspiration. Using SMAP data, we demonstrated that, introducing nonlinearity in a traditional soil model help capture aggressive vs conservative vegetation water consumption.

I just published Version 1.6. The main update is that the source data for CAMELS-AUS was upgraded to CAMELS-AUS v2. This means more basins (561 vs 222) and more recent streamflow data (2022 vs 2014).

Starting on bsky with a new preprint: "How to deal w___ missing input data"
doi.org/10.31223/X50...

Missing input data is a very common challenge in deep learning for hydrology: weather providers have outages, some data products start later than others, some only exist for certain regions, etc.
Different scenarios for missing input data: outages at individual time steps (top), data products starting at different points in time (middle), and local data products that are not available for all basins (bottom). All of these scenarios reduce the number of training samples for models that cannot cope with missing data (yellow, small box), while the models presented in this paper can be trained on all samples with valid targets (purple, large box).

GRAD POSITION: MSc position aquatic ecology and conservation at Laurentian University w/ flexible start date. Contact Brie Edwards (see ALT text) for more details #AcademicSky
We are currently seeking a MSc domestic student (i.e. Canadian citizen or permanent resident) to join a cohort of newly recruited HQP. The project will focus on developing and testing novel stream biomonitoring methods incorporating eDNA to assay community membership from microbes to fish. These rapid bioassessment techniques will be tested against traditional approaches in their ability to produce functional, community and multi-trophic indicators of ecosystem integrity and biodiversity along a gradient of impact recovery. The student will be hosted at Laurentian University (Dr. Brie Edwards) and co-supervised by Dr. Erik Emilson (Natural Resources Canada). Field work will begin in Spring of 2025 and will be conducted in the Sudbury area. As such we are recruiting a student interested in starting May 2025. Ideal candidates will have a strong background in aquatic ecology and an interest in benthic bioindicators, molecular techniques, and population and community responses to environmental change. Quantitative skills in statistical analysis are desired but can be provided through training programs at the respective institutions. Interested students should send a CV, cover letter expressing interest and relevant skills, as well as a copy of unofficial transcripts to Brie Edwards (bedwards2@laurentian.ca). Please include “CRADLES graduate interest” as the subject line.

If you are still around and have interest in #drought #groundwater at CONUS scale, stop by our talk today at 2:56p in 145. Apparently, it has been "highlighted" by the convenors, and @matthiasprenger.bsky.social tells me it is not a bad thing 😅

@lireactivewater.bsky.social delivers this year’s Witherspoon lecture during #AGU24. She describes scientific models like novels. Novels allow us to study the deeper truths of the human existence. Scientific models help us explore deeper truths of science.

Using all the activity here from #AGU24 to highlight our #EGU25 session on "Deep learning in hydrology" that is open for abstract submission.
kratzert.bsky.social Frederik Kratzert @kratzert.bsky.social · Nov 22
Are you working on the intersection of hydrology and deep learning? Consider submitting your abstract to our #EGU25 session on "Deep Learning in Hydrology".

See detailed session description at meetingorganizer.copernicus.org/EGU25/sessio...
Promotional image for the "deep learning in hydrology" session. On the left, shows the following description: "We welcome abstracts related to novel theory development, new methodologies, or practical applications of deep learning in hydrological modeling and process understanding.". On the right, shows an abstract visualization of a brain with some elements of an electrical circuit. There is a waterfall coming out from the middle part of that brain, forming a river that flows towards the front.
