# Numpy Array Daily Profile Parameter Recorder

## General Description

Recorder for an annual profile from a *Parameter*.

This recorder stores a daily profile returned by a specific parameter. For each day of the year it stores the value encountered for that day during a simulation. This results in the final profile being the last value encountered on each day of the year during a simulation. This recorder is useful for returning the daily profile that may result from the combination of one or more parameters. For example, during optimisation of new profiles non-daily parameters (e.g. *RbfProfileParameter*) and/or aggregations of several parameters might be used. With this recorder the daily profile used in the simulation can be easily saved.

The data is saved internally using a memory view. The data can be accessed through the *data* attribute or *to\_dataframe()* method. [API Reference](https://pywr.github.io/pywr-docs/master/api/generated/pywr.recorders.NumpyArrayDailyProfileParameterRecorder.html)

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://water-strategy.gitbook.io/waterstrategy/modeling-basics/recorders/numpy-array-recorders/numpy-array-daily-profile-parameter-recorder.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
