Survey questions for an article titled, "Operationalizing Global Reservoir & Lake Hydrology to Detect Localized Climate Fingerprints in a Warming Climate" by Solomon Vimal and Vijay P. Singh
The goal of this survey is to understand and gauge better a strategy to detect regional scale climate change signatures from lakes and create a dashboard for monitoring climate change signatures from lakes.

Lakes and reservoirs are particularly suited for detecting in-land climate change signatures because they are contiguous and homogeneous (unlike more heterogeneous soil surfaces). Their anomalous and unique, yet well-known, properties make them a low-hanging fruit to detect local climate change signatures.

The below questions are crafted for experts in various areas: scholars of hydrology, climate scientists, limnologists, watershed scientists, glaciologists, environmental scientists, lake bio-geo-chemists, government or non-profit community associations that manage lakes including, regional initiatives (e.g. Arctic/Tibetan/Laurentian Great Lake) who may benefit from developing climate fingerprint detection tools using better understanding of the hydrology of lakes.

With your expert opinions, we aim towards creating a lake and climate signature monitoring dashboard. We hope to use lake observations from space (e.g. low-resolution long-term observations of Landsat to high-resolution recent cube sat data) which can be viewed together with hydrology and climate signatures of the region that contributes to lake change. In so doing, we may better quantify local scale  in-land climate change signatures. Such signatures may be a proxy (or sentinel) for regional (or local) climate change impacts because lakes are ubiquitous and be-sprinkled all over the heterogenous global land surface.

What is your professional affiliation?
Approximately how many years of experience do you have in any of these areas (including graduate school time): hydrology, limnology, meteorology, water or climate science? *
Perception & motivation: Why are lakes important for you or your institute/employer?
From your understanding, what is the direction of long-term change in lakes due to climate change (where there is no human influence)?
What are the challenges and opportunities you find in the area of using lake change detection from space as a climate change fingerprint?
Other than lakes, what are some integrated in-land signatures of climate change we can readily observe from space?
What are the critical variables one should keep in mind while interpreting lake changes in a warming climate?
What is currently missing in lake hydrology processes knowledge or data on critical variables?
What information do you need to conclusively say that climate change is at play in the lakes you observe to be changing?
What are some confounding factors one should consider while detecting climate change finger prints from lakes?
What climate/water/atmospheric indices should be considered in interpreting lake trends (regionally to globally)?
Most inland lakes are subject to human interference, such as withdrawal of water for water supply, navigation, pollution through waste disposal, sedimentation in the lake drainage basin, etc. Climate change signatures can still be observed but are mixed with those of human interference. Under this condition, how would you go about detecting climate change signature from lakes?
What are the primary educational and training needs  for those who study climate change signatures from lakes? What are the key gaps in knowledge of young and experienced hydrologists?
[optional] What trend detection method(s) do you use for understanding long-term lake changes? Are you aware of the ball-park magnitude of the method's Type-I and Type-II errors? Can you comment on how important these errors might be? Which of these errors are more important to you and why?
Please comment on the organizational, systemic or resource constraints in relation to the thematic areas here (i.e. the domain of lake hydrology, climate, water resources)? Can you think of any scholar/scientist who has commented on these in their scientific writing?
Do you have any additional thoughts to share with us?
Would you be willing to have a follow-up chat with us over a 15-min Zoom call?
A copy of your responses will be emailed to the address you provided.
