In the past, GNOME +accepted only specific formatting for gridded data in netCDF files, and this data was generally unavailable to other +parts of the model. Adding a new data format or grid type was a difficult affair that required diving deep into the legacy C components. + +Environment objects were conceptualized as a flexible and easy-to-develop representation for gridded data that would +dramatically reduce the difficulty of handling the many different formats and be usable and sharable throughout the model. + +Overview +----------------- +An important perspective to take is an abstracted view of what gridded data represents. You can imagine any gridded data as a scalar +field, where each point in space and time is associated with a value. Because the data is discrete on specific points in +space, the value of a point between these data points must be determined by some sort of interpolation. + +An environment object implements an association between a data variable (such as a netCDF Variable, or numpy array) and a +Grid, Time, and Depth (representing the data dimensions in space and time) and does interpolation across them. By combining and/or imposing conditions on these environment objects, many natural processes can be represented. In addition, if possible, the Grid, Time, and Depth may be shared among environment objects, which provides a number of performance and programmatic benefits. +The core functionality of an environment object is it’s ‘EnvObject.at(points, time)’ function. The intent of this +function is to provide the interpolated value of the data at each point at the specified time. By extending and +overriding this function, more advanced behavior can be implemented. An example of this is the IceAwareCurrent, +described later in this paper. \ No newline at end of file From 2943917d6d0d81d2d219714b929b7d6351730c3c Mon Sep 17 00:00:00 2001 From: "James L.

As close as I could think of for -InfTime and +InfTime But it is now failing with an ou tof range error for making a time out of the value. I used: std::numeric_limits::max() To get the max value, but I guess that isn't working (on 64 bit OS-X) also -- I used 0 for minimum time, but maybe that should be negative some_very_large_value Maybe this logic should be pushed to the Cyton/Python layer. donpt merge this without resolving these issues! --- lib_gnome/OSSMTimeValue_c.cpp | 207 +++++++++--------- py_gnome/gnome/movers/wind_movers.py | 10 +- .../unit_tests/test_environment/test_wind.py | 17 ++ 3 files changed, 130 insertions(+), 104 deletions(-) diff --git a/lib_gnome/OSSMTimeValue_c.cpp b/lib_gnome/OSSMTimeValue_c.cpp index 9ee8cd1fc..db5e5e52e 100644 --- a/lib_gnome/OSSMTimeValue_c.cpp +++ b/lib_gnome/OSSMTimeValue_c.cpp @@ -23,7 +23,7 @@ using namespace std;
