I am looking for a rather high resolution data set in tabular form (no shapefile, a .txt, .csv, or .dbf) on certain natural hazards in California.

The natural hazards I am particularly interested in are drought and flood. Along these lines I look for variables of something like

  • Precipitation
  • Soil Moisture
  • Drought Indices
  • Days of Extreme Heat
  • Temperatures
  • Baseflow
  • Risk indices for drought/flood
  • Risk for wild fire
  • Coastal Flooding
  • Area flooded if sea level rises
  • Population of people affected by drought/flood

The number of variables should be >6. The background is I want to illustrate a new statistical method.

The data set should consist any of the following

  1. A spatial historical time series.
  2. A spatial times series of projections (e.g. A2 or B1 scenarios of IPCC, some bias-reduced downscaled projection or so).

For this lower the resolution, the better (say from a 5x5 km grid in lattitude longitude and daily values from 2000 onwards or so). I would however also be fine however with annual (or even more coarse resolution) data on census block or county level.

I've been looking at a couple of non-profit and governmental websites. But most data were either in form of maps or didn't meet the above criteria. Whenever I found data meeting the above criteria, I usually hit some authorization dialogue.

The closest I got to what I wanted was Cal-Adapt, the map on precipitation is a perfect example of the data that I'd like to have in tabular form.

They have a section tabular data downloads which would be exactly what I need, if it were not for the mildly irritating fact that one has to select grid cells to download the data for. Since I want all of the data I'd have to click on all the cells, which - with a resolution of a 12km x 12km and the size of CA being 423,970 km^2 - is rather tedious. But this means these data are out there and they are made available to the public, I just need the raw data (or an equivalent).

I'm also aware of these data sets but didn't have the time to investigate them.

Check out the content at Data Basin, which has a lot of California data.
