The Weather Monitor System in Arc Raiders offers players a long-term progression project introduced during the Shrouded Sky update. Designed as a permanent addition to Speranza, this initiative encourages Raiders to explore hazardous Topside zones and turn in vital scavenged components. By understanding where each required item spawns, players can streamline their progression and unlock exclusive rewards efficiently.
Understanding the Weather Monitor System Structure
This multi-stage project requires players to submit distinct sets of resources across five phases: Atmospheric Pressure, Sunlight, Precipitation, Humidity, and Temperature. Each stage demands four specific item groups that must be fully completed before receiving stage-specific loot. Because progress is saved permanently, players can gather required resources gradually without worrying about timed event deadlines.
Submitting resources in batches unlocks powerful equipment, crafting materials, and consumables at each tier. Finishing all five tiers rewards players with 250 Raider Tokens and the unique Anemometer Backpack Charm. Stash management plays a crucial role, as hoarding materials early saves significant time during later project phases.
Scavenging Early Phase Materials in Topside
The initial phase focuses on basic components like Plastic Parts, Metal Parts, Oil, and ARC Alloy. Basic structural items drop frequently throughout industrial locations or can be purchased directly from merchants in Speranza. Defeating basic ARC enemies across any Topside map will yield necessary ARC Alloys.
As you progress into the Sunlight phase, you will need to search technological and electrical loot sectors for items like Wires and Sensors. Searching server desks or prying open electronic hubs yields high drop rates for sensor components. Snitch Scanners can be retrieved by destroying roaming Snitch drones before they alert nearby patrols.
Locating Rare Drops and ARC Monster Components
Later stages demand specialized drops from newly introduced ARC threats such as the Comet and Firefly. The Comet Igniter drops upon defeating a Comet ARC unit, but players must eliminate the target before it self-destructs to secure the loot. Similarly, the Firefly Burner is harvested from Firefly drones, best targeted by shooting their weak gas tanks from a safe distance.
Specific rare materials like the Water Pump and Fine Wristwatch are hidden within specialized sub-locations. Search the Hydrophonic Dome Complex within Dam Battlegrounds for industrial pump units. Residential zones and commercial loot caches provide the highest chance of finding wristwatches and camera lenses.
Tips for Efficient Farming and Progress
Deploying into Topside during active Hurricane map conditions significantly increases spawning rates for unique ARC threats. Equipping high armor-penetration weaponry ensures clean combat encounters, preventing loot destruction during intense firefights. Focusing efforts on target-specific zones accelerates material collection across all five project phases.
