CROCUS Data Access

Python notebooks and utilities for accessing sensor data from the CROCUS (Community Research on Climate and Urban Science) network of Waggle/Sage nodes deployed across Chicago, Illinois.

Contents

• crocus_data_access.ipynb — Main notebook demonstrating how to query, wrangle, and visualize data from CROCUS sensors including the Vaisala WXT536 weather transmitter, Vaisala AQT530 air quality transmitter, Hydreon RG-15 rain gauge, SFM1x sap flow meters, and ICT International MFR soil nodes.

• sage_utils.py — Query functions that wrap the Sage Data Client and return clean wide-format DataFrames suitable for analysis and plotting.

• crocus_sites.py — Site metadata for all CROCUS field locations including coordinates, sensor availability, and instrument serial number mappings.

Installation

pip install -r requirements.txt

Usage

from crocus_sites import NEIU, CSU, NU   # import any site
SITE = NEIU                               # set the active site
