title: Data, simulations/projections, and supporting materials for simulated hydrologic responses to climate-change projections for the Lake Tahoe basin: subbasin-scale results

description: This dataset contains data, simulations, projections, and supporting
 materials associated with simulated hydrologic responses, at the scale of
 60 subbasins comprising the Lake Tahoe Basin, California and Nevada, to a
 16-member ensemble of statistically-downscaled projections of climate
 change, 1950-2099. The process and results are described in detail in
 Dettinger, M., & Rajagopal, S., 2023, Simulated hydrologic
 responses to climate-change  projections for the Lake Tahoe
 Basin: Desert Research Institute Publication 41292, 99 p.,  
 which is included here.    The dataset as presented here
 contains 6 files, including one large zipped file that itself contains
 some 1,975 files, mostly simple text files of data, simulation outputs,
 and analytical results organized into dozens and dozens of subdirectories
 to allow specific elements to be identified and isolated. Beyond this
 large collection, the zipped file also contains copies of the report(s),
 selected supporting documents, graphical files, codes, and copious
 #readme.txt files to orient the user. 
description: Simulations with PRMS hydrologic model of the Lake Tahoe Basin,
 daily resolutions on 300 m grid, compiled for each of 60 subbasins
 comprising the whole basin. Models, simulations, model validations,
 projections, and results described in detail in the subject report
 (available online and as a pdf file in the top level of this data
 set).

 This dataset includes a zipped file (5 Gb, expanding to 15 Gb when opened)
 containing 1975 files of data, simulations, projections and supporting
 materials associated with simulated hydrologic responses, at the scale of
 60 subbasins comprising the Lake Tahoe Basin, California and Nevada, to a
 16-member ensemble of statistically-downscaled projections of climate
 change, 1950-2099. The process and results are described in detail in
 Dettinger, M., & Rajagopal, S., 2023, Simulated hydrologic
 responses to climate-change  projections for the Lake Tahoe Basin: Desert
 Research Institute Publication 41292, 99 p. Along with this large data
 file, copies of the report above, the executive summary thereof, and a
 powerpoint presentation summarizing results are included here (and in the
 zipped file). Author/Principal Investigator Information Name: Michael

DATA & FILE OVERVIEW File List: See below (horizontal line). Are there multiple versions of the dataset? no METHODOLOGICAL INFORMATION Methods for production and analysis of data (including relevant data inputs and codes) here described at some length in  the corresponding DRI Publication 41292, and/or in #readme.txt files in sub-sub-directories throughout. Standards and calibration information, if appropriate: Chapter 3 of DRI Publication 41292. ======================================================================================================================= The zipped file contains the data described in associated reports, including elements, data, and background from the Tahoe Climate-Change Projections project for your use and in hopes that you will take these results and recraft them to meet your own needs. The full reports and executive summary are included here in pdf form: #\_41292-Tahoe\_Projections\_Final\_Report.pdf #\_Tahoe\_Projections\_Exec\_Summary.pdf The historical\_verificationflows\_online subdirectory contains the data files used in section 3 of the report, as the raw materials for assessing the verifications of the historical performance of the PRMS model (and PRMS\_GCM combinations). See the #\_README.txt file for more details. The key\_reports\_resources subdirectory contains some background materials regarding models, past applications, and so on. These elements can be hard to find, and so have been included here. The reports\_figs\_online subdirectory contains raw materials (underlying data), analysis and formatting codes, and other tidbits associated with each of the figures in the reports. The idea is that you can rework them, calculate your own statistics, and change the questions answered by the report figures using these materials. See README.txt files in each sub-sub-directory. See readme files in each sub-subdirectory to navigate all the many data sets, codes, and figures included. The subbasins\_projxns\_online subdirectory contains all of the subbasin-level projections of hydrologic outputs and meteorological inputs, so that you can do whatever you want or need with the simulations results at the 60 subbasins at daily levels for all the simulations. Simple example codes are provided to get you started. See the #\_README.txt file for information about what is here. The tahoe\_figures subdirectory contains pdf (and some png) files for each of the new figures in the reports. These are about as crisp and clean as we can offer. The Tahoe\_PRMS.7z file is a compressed copy of the PRMS model used. The tahoe\_subbasins\_online.qgs file is a copy of the basic GIS information for this study as stored by the open-access QGIS software (used in this study).
