Snowfall Equivalent
This endpoint accesses historical and projected modeled decadal summaries of annual snowfall equivalent (SFE) for Alaska. Note that SFE has a very specific meaning in a modeling context: it is the product of the fraction of days in a month with precipitation falling as snow and the total monthly precipitation. That product (monthly) is then summed to create a single annual total SFE value. The SFE values provided here are millimeters of water.
Summary queries for SFE
Query the historical SFE min, mean, and max:
Example: /mmm/snow/snowfallequivalent/historical/61.5/-147
Query the projected SFE min, mean, and max:
Example: /mmm/snow/snowfallequivalent/projected/61.5/-147
Query both the historical and projected SFE min, mean, and max:
Example: /mmm/snow/snowfallequivalent/hp/61.5/-147
Results from the queries above will look like this:
{
"historical": {
"sfemax": 4876,
"sfemean": 3701,
"sfemin": 2946
}
...
}
The above output is structured like this:
{
<summary time period type, "historical" or "projected">: {
"sfemax": <max SFE value across all models, scenarios, and decades>,
"sfemean": <mean SFE value across all models, scenarios, and decades>,
"sfemin": <min SFE value across all models, scenarios, and decades>
}
...
}
Comprehensive queries for SFE
Query both the historical and projected SFE values for all models, scenarios, and decades (1910-1919 through 2090-2099):
Example: /mmm/snow/snowfallequivalent/all/61.5/-147
Results from the query above will look like this:
{
"CRU-TS": {
"historical": {
"1910-1919": {
"SFE": 3801,
}
...
}
...
}
...
}
The above output is structured like this:
{
<model>: {
<scenario>:{
<decade>: {
"SFE": <annual total sfe value>,
}
...
}
...
}
...
}
