Narrative: Departed ZZZ and climbing through approximatley FL220 First Officer saw smoke in the cockpit. I noticed smoke at that time coming from behind the First Officer. Oxygen Masks were donned and communications established. First Officer was already flying so I assigned him flying and ATC Communication duties. I start Quick Action Items and QRH procedures.FO (First Officer) notified ZZZ Center under my direction and navigated back towards ZZZ airport.QRH procedures were performed methodically and we found the source of smoke to be Air Conditioning problems associated with Pack 1.Smoke went away immediately after accomplishing QRH procedures. Then established communications with flight attendants through interphone system. They stated NO Smoke in the cabin. Informed them we had smoke in the cockpit that was contained and were returning to ZZZ.I asked them to prepare for a precautionary landing and gave an ETA. Then made a PA to passengers that we had a maintenance situation that required a return to ZZZ.We reviewed the non-routine landing checklist in QRH. Rest of the flight was normal SOP. No Limitations were exceeded nor any flight parameters. ie. Heading; altitude; directions in generalWe can't avoid these types of situations but I will say; the resources and procedures available to us contained the situation quickly. I can't think of anything different that would have helped in this situation. Communication was outstanding within the crew; ATC; emergency services in ZZZ and the company.


Second narrative: On departure out of ZZZ during initial climb out; we experienced the flight deck temperature increasing substantially. I was the Flying Pilot and the Captain was the Non-Flying Pilot. The Captain adjusted the temperature control to try and cool off the cockpit. Approximately 10 minutes into the flight climbing out of FL220 for an assigned altitude of FL280; I noticed smoke in the cockpit. I immediately donned my oxygen mask and established communication with the Captain who was in the process of donning his oxygen mask. Once we established effective communication; he gave me control of radio communications and I stated that I have positive control of the aircraft as well as radio communications. The Captain then went to the quick action checklist and found the smoke/avionics smoke/fumes procedure. The number 2 item on that particular procedure was to land ASAP if smoke was confirmed which it was. The Captain asked me to inform air traffic control. The Captain continued the checklist and I immediately [notified] Center. I told Center that we needed to also level off which I did at FL240. ATC asked what our intentions were and I stated that we needed to return to ZZZ. I was then given a left hand turn direct to ZZZ. I also requested a descent to FL100. I then provided ATC with souls on board and fuel remaining. We had 109 souls on board and 22;600 pounds of fuel. The Captain continued the checklist and made communication with the flight attendants to determine the conditions in the cabin. According to the flight attendants; there wasn't any smoke in the cabin but they did notice an unusual odor. We determined that the air ventilation and conditioning was the probable cause for smoke in the cockpit. Once the Captain selected the PACK 1 OFF; the smoke dissipated and went away. The Captain completed the checklist and then took back the radio communications while I continued to fly the aircraft. He then communicated to the passengers of our return to ZZZ. The Captain then contacted the company to let them know our situation and our intentions. He also made sure to brief the flight attendants of our return to ZZZ. During this time of checklist; I was getting weather and setting up for a visual approach backed up by [the] ILS into ZZZ. Approach control gave us priority landing. ARFF (Airport Rescue and Fire Fighting) was in position on the far end of [the] runway as we approached. We landed without any further complications and came to a complete stop once exiting the runway and re-evaluated our situation before we continued to parking. I advised Tower that we had no other problems and no smoke was present. We then taxied to the gate and deplaned the passengers. We believe the event occurred because the PACK 1 had and overheat condition. We believe this was the reason why we had smoke in the cockpit considering we completed the appropriate checklist and was able to ventilate the cockpit and remove the smoke by selecting the PACK 1 OFF. The only suggestion I can make is to be more attentive to the temperature within the cabin and cockpit prior to takeoff and doing a last minute assessment to determine if conditions are uncomfortable or out of a normal range.


Synopsis: A319 Flight Crew reported smoke entered the cockpit during climb that dissipated when Pack 1 was selected to off.
