Lightweight Python package for calculating the atmospheric transmission

## Overview

[simpleatm] is a Python package which calculates (sub)millimeter atmospheric transmission as a function of precipitable water vapor (PWV) and frequency.

The package includes pre-calculated transmission datasets at various observation sites by the [ATM model] (Pardo et al. 2001).

Moreover, since a dataset is loaded as the [xarray]'s DataArray format, interpolation, plotting, and saving features are provided by default.

Therefore, [simpleatm] would be useful in fast and approximate sensitivity calculation of a telescope instrument.

## Requirements

- **Python:** 3.6, 3.7, or 3.8 (tested by the authors)

- **Dependencies:** See [pyproject.toml](https://github.com/deshima-dev/simpleatm/blob/master/pyproject.toml)

## Installation

```shell

$ pip install simpleatm

```

## Usage

To be updated after the release of [v0.2.0](https://github.com/deshima-dev/simpleatm/milestone/2).

## For developers

```shell

$ git clone https://github.com/deshima-dev/simpleatm.git

$ cd simpleatm

$ scripts/setup

```
